The article was titled 《All-Inorganic Perovskite Quantum Dots Based on InX3-Trioctylphosphine Oxide Hybrid Passivation Strategies for High-Performance and Full-Colored Light-Emitting Diodes》.Application In Synthesis of Indium(III) bromide The article contains the following contents:

All-inorganic perovskite quantum dot (PeQD) light-emitting diodes (QLEDs) are promising candidates for the next-generation flat-panel displays and semiconductor lighting technol. However, the stability issues severely limit their com. applications. In this study, highly stable CsPbX3 (X = Cl, Br, I) PeQD films were prepared using InX3 (X = Cl, Br, I) and trioctylphosphine oxide (TOPO) as inorganic-organic hybrid ligands to passivate the surface defects of PeQDs. The obtained InX3-TOPO-CsPbX3 PeQDs not only have high photoluminance quantum yields (PL QYs) and very narrow emission (14-35 nm) but also possess long-term stability. This is mainly due to the synergistic effect of InX3 and TOPO inorganic-organic surface ligand passivation, which can effectively inhibit the halogen vacancy and reduce the surface defect of PeQDs. In addition, the chem. states of InBr3-TOPO-CsPbBr3 PeQDs were analyzed by XPS technol. and it was found that InX3-TOPO synergistic surface passivation can effectively reduce the Pb=O bond in the crystal lattice. Moreover, full-colored perovskite QLEDs based on InX3-TOPO-CsPbX3 PeQDs were achieved by using ZnO/PBD as the double electron transport layer, NiO/TFB as the double hole transport material, and InX3-TOPO-CsPbX3 PeQDs as the light-emitting layer. The EQE (%) and luminance (cd m-2) of red, green, and blue QLEDs based on these InX3-TOPO-CsPbX3 PeQDs were 8.2% and 9080 cd m-2, 7.8% and 18,600 cd m-2, and 1.62% and 164 cd m-2, resp. This cooperative effect based on the InX3-TOPO hybrid passivation strategy will open a way for the preparation of highly efficient, stable, and color-tunable perovskite QLEDs. In the experiment, the researchers used many compounds, for example, Indium(III) bromide(cas: 13465-09-3Application In Synthesis of Indium(III) bromide)

A transition-metal-free aminocyanation of aryl alkynes has been achieved using indium tribromide, InBr3 or B(C6F5)3 as a Lewis acid. This aminocyanation protocol features with non-toxic cyanide source, a good substrate scope and potentially valuable aminocyanation products. Mechanistic studies reveal the complex formation between Lewis acid and alkyne to produce in situ alkyne nitrile as a key intermediate.

In 2019,Journal of Physical Chemistry C included an article by Chen, Shanbao; Huang, Chengxi; Sun, Huasheng; Ding, Junfei; Jena, Puru; Kan, Erjun. Category: bromides-buliding-blocks. The article was titled 《Boosting the Curie temperature of two-dimensional semiconducting CrI3 monolayer through van der Waals heterostructures》. The information in the text is summarized as follows:

The integration of ferromagnetic and semiconducting properties in a single 2-dimensional (2D) material has been recognized as a fertile ground for fundamental science as well as for practical applications in information processing and storage. CrI3 monolayer has recently drawn much attention due to its 2D long-range ferromagnetic (FM) order. However, its Curie temperature (TC) is too low (∼45 K) for practical spintronic applications. Here, the authors show that the in-plane FM coupling of CrI3 can be remarkably enhanced by constructing a 2D heterostructure where CrI3 monolayer is supported on a nonmagnetic normal semiconductor/insulator substrate. Choosing MoTe2 monolayer as a substrate, the authors find that the CrI3/MoTe2 2D heterostructure is an intrinsic semiconducting ferromagnet with TC of ∼60 K. The TC can be further increased to ∼85 K by applying an out-of-plane pressure of ∼4.2 GPa. The doubling of the TC in this 2D heterostructure comes from the introduction of extra spin superexchange (Cr-Te-Cr) paths. These findings provide a promising pathway to improve ferromagnetism in 2D semiconductors, which can stimulate further theor. and exptl. interest. In the experimental materials used by the author, we found Indium(III) bromide(cas: 13465-09-3Category: bromides-buliding-blocks)

In 2019,Energies (Basel, Switzerland) included an article by Ghodrat, Maryam; Samali, Bijan; Rhamdhani, Muhammad Akbar; Brooks, Geoffrey. Application of 13465-09-3. The article was titled 《Thermodynamic-based exergy analysis of precious metal recovery out of waste printed circuit board through black copper smelting process》. The information in the text is summarized as follows:

Exergy anal. is one of the useful decision-support tools in assessing the environmental impact related to waste emissions from fossil fuel. This paper proposes a thermodn.-based design to estimate the exergy quantity and losses during the recycling of copper and other valuable metals out of electronic waste (e-waste) through a secondary copper recycling process. The losses related to recycling, as well as the quality losses linked to metal and oxide dust, can be used as an index of the resource loss and the effectiveness of the selected recycling route. Process-based results are presented for the emission exergy of the major equipment used, which are namely a reduction furnace, an oxidation furnace, and fire-refining, electrorefining, and precious metal-refining (PMR) processes for two scenarios (secondary copper recycling with 50% and 30% waste printed circuit boards in the feed). The results of the work reveal that increasing the percentage of waste printed circuit boards (PCBs) in the feed will lead to an increase in the exergy emission of CO2. The variation of the exergy loss for all of the process units involved in the e-waste treatment process illustrated that the oxidation stage is the key contributor to exergy loss, followed by reduction and fire refining. The results also suggest that a fundamental variation of the emission refining through a secondary copper recycling process is necessary for e-waste treatment. The results came from multiple reactions, including the reaction of Indium(III) bromide(cas: 13465-09-3Application of 13465-09-3)

《Zinc/Indium Bimetallic Lewis Acid Relay Catalysis for Dehydrogenative Silylation/Hydrosilylation Reaction of Terminal Alkynes with Bis(hydrosilane)s》 was written by Tani, Tomohiro; Sohma, Yudai; Tsuchimoto, Teruhisa. Reference of Indium(III) bromideThis research focused onzinc indium Lewis acid catalyst dehydrogenative silylation alkyne hydrosilane; disilanaphthalene preparation; disilaindane preparation; disilylalkene preparation; hydrosilylation intramol dehydrogenative silylation zinc indium catalyst; bismuth catalyzed Hiyama cross coupling ether formation iododesilylation. The article conveys some information:

When mixed with two different Lewis acid catalysts of Zn and In, terminal alkynes react with bis(hydrosilane)s to selectively provide 1,1-disilylalkenes from among several possible products, by way of a sequential dehydrogenative silylation/intramol. hydrosilylation reaction. Adding a pyridine base is crucial in this reaction; a switch as a catalyst of the Zn Lewis acid is turned on by forming a Zn-pyridine-base complex. A range of the 1,1-disilylalkenes can be obtained by a combination of aryl and aliphatic terminal alkynes plus aryl-, heteroaryl-, and naphthyl-tethered bis(hydrosilane)s. The 1,1-disilylalkene prepared here is available as a reagent for further transformations by using its C-Si or C:C bond. The former includes Hiyama cross-coupling, Bi-catalyzed ether formation, and iododesilylation; the latter includes double alkylation and epoxidation Mechanistic studies clarified the role of the two Lewis acids: the Zn-pyridine-base complex catalyzes the dehydrogenative silylation as a 1st stage, and, following on this, the In Lewis acid catalyzes the ring-closing hydrosilylation as a 2nd stage, thus leading to the 1,1-disilylalkene.

Pelayo; Sargent, Edward H. published an article in Advanced Materials (Weinheim, Germany). The title of the article was 《Fast Near-Infrared Photodetection Using III-V Colloidal Quantum Dots》.Name: Indium(III) bromide The author mentioned the following in the article:

Colloidal quantum dots (CQDs) are promising materials for IR (IR) light detection due to their tunable bandgap and their solution processing; however, to date, the time response of CQD IR photodiodes is inferior to that provided by Si and InGaAs. It is reasoned that the high permittivity of II-VI CQDs leads to slow charge extraction due to screening and capacitance, whereas III-Vs-if their surface chem. can be mastered-offer a low permittivity and thus increase potential for high-speed operation. In initial studies, it is found that the covalent character in indium arsenide (InAs) leads to imbalanced charge transport, the result of unpassivated surfaces, and uncontrolled heavy doping. Surface management using amphoteric ligand coordination is reported, and it is found that the approach addresses simultaneously the In and As surface dangling bonds. The new InAs CQD solids combine high mobility (0.04 cm2 V-1 s-1) with a 4x reduction in permittivity compared to PbS CQDs. The resulting photodiodes achieve a response time faster than 2 ns-the fastest photodiode among previously reported CQD photodiodes-combined with an external quantum efficiency (EQE) of 30% at 940 nm.

The development of batteries and fuel cells has brought to light a need for carbon anode materials doped homogeneously with electrocatalytic metals. In particular, combinations of electrocatalysts in carbon have shown promising activity. A method to derive functional carbon materials is the pyrolysis of metallopolymers. This work describes the synthesis of a bifunctional phosphonium-based system derived from a phosphane-ene network. The olefin functionality can be leveraged in a hydrogermylation reaction to functionalize the material with Ge. Unaffected by this radical addition, the bromide counterion of the phosphonium cation can be used to subsequently incorporate a second metal in an ion-complexation reaction with CuBr2. The characterization of the polymers and the derived ceramics are discussed.Indium(III) bromide(cas: 13465-09-3Synthetic Route of Br3In) was used in this study.

Tsukamoto, Takamasa; Imaoka, Takane; Yamamoto, Kimihisa published an article in 2021. The article was titled 《Unique Functions and Applications of Rigid Dendrimers Featuring Radial Aromatic Chains》, and you may find the article in Accounts of Chemical Research.Electric Literature of Br3In The information in the text is summarized as follows:

Conspectus: Dendrimers, which are highly branched polymers and regarded as huge single mols., are interesting substances from the aspect of not only polymer chem. but also mol. chem. Various applications in material science and life science have been investigated by taking advantage of the radially layered structures and intramol. nanospaces of dendrimers. Most dendrimers have flexible structures that originate from their organic chains which contain many sp3-type atoms, while relatively rigid dendrimers composed only of sp2-type atoms have rarely been reported. It has been recently clarified that such rigid dendrimers exhibit a specific aromatic property not found in other materials. Dendritic phenylazomethines (DPAs), as one of the rigid dendrimers, have only sp2-type C and N atoms and possess a radially branched π-conjugation system in their own macromol. chains. Such geometric and electronic structures heighten the electron d. at the core of the dendrimer and induce an intramol. potential gradient, which affords unique reactivities that lead to extraordinary functions. This unique property of the rigid dendrimers can be regarded as a new atypical electronic state based on radial aromatic chains not found in conventional aromatic compounds containing spherical aromaticity, Mobius aromaticity, metal aromaticity, and conductive polymers. Therefore, this as-yet-unknown characteristic is expected to contribute to the further development of fundamental and materials chem. In this Account, we highlight the rigid DPA dendrimers and their peculiar atomically precise and selective assembly behaviors that originate from the radial aromatic chains. One of the most noteworthy attainments based on the radial aromatic chains is the precise synthesis of a multimetallic multinuclear complex of a dendrimer containing a total of 13 elements. Next, we describe the electrochem. and catalytic functionalization of such multinuclear dendrimer complexes and the construction of supramol. nanoarchitectures by the polymerization of DPAs. These complexes exhibit encapsulation-release switching of guests and additive-free catalytic ability similar to proteins and enzymes. Such selective and accurate control of the intramol. assembly of guests and the intermol. arrangement of hosts realized by the radial aromatic chains of dendrimers will enable supramol. chem. and biochem. to be linked from a new aspect. In addition, the multimetallic multinuclear complexes of dendrimers afford a novel approach to precisely synthesize subnanoparticles with ultrasmall particle sizes (1 nm) that have been tech. difficult to obtain by conventional nanotechnol. We discuss the method for the synthesis of these subnanoparticles with well-controlled atomicity and composition using DPA complexes as a template, and recent advances to reveal their specific phys. and chem. properties. These results suggest that the unique electronic states induced in such radial aromatics could play an important role in the development of next-generation chem. In addition to this study using Indium(III) bromide, there are many other studies that have used Indium(III) bromide(cas: 13465-09-3Electric Literature of Br3In) was used in this study.
