Location effect of triptycene on the photovoltaic performance of carbazole-based dyes was written by Yan, Mao;Zhu, Yi-Zhou;Yan, Yi-Qiao;Wang, Qun-Hui;Yin, Guan-Lin;Zheng, Jian-Yu. And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 2022.SDS of cas: 128-08-5 This article mentions the following:

Due to the unique three-dimensional spatial structure and special electronic properties, triptycene has been applied in dye-sensitized solar cells. Herein, two dyes JY76/JY77 featuring triptycene at the different substitution position of carbazole donor have been synthesized, and location effect of triptycene on the photovoltaic performance of devices has been investigated. Lateral derived triptycene endows JY77 much more enhanced capability of impeding the interface charge recombination than JY76 which triptycene was decorated at terminal. Finally, JY77-sensitized solar cells exhibit around 20% higher power conversion efficiency (PCE) than that of JY76. The photovoltaic properties are further tuned by co-sensitization strategy, and better PCEs are obtained. Under AM 1.5G irradiation, cells fabricated by the synergic adsorption of JY77 and JY75, achieve the highest PCE of 8.01%. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5SDS of cas: 128-08-5).

1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions.

Solid superacids catalyzed organic synthesis. 3. Nafion-H catalyzed condensation of acetophenone derivatives. A preparative route to 1,3,5-triarylbenzenes. was written by Yamato, Takehiko;Hideshima, Chieko;Tashiro, Masashi;Prakash, G. K. Surya;Olah, George A.. And the article was included in Catalysis Letters in 1990.Synthetic Route of C24H15Br3 This article mentions the following:

Nafion-H, a perfluorinated resin sulfonic acid, catalyzes condensation of acetophenones I (R = H, R¹ = H, alkyl, MeO, Br, Cl; R = Br, R¹ = H) to provide 1,3,5-triarylbenzenes under relatively mild conditions. Reactions are clean and water formed as byproduct does not deactivate the catalyst. However, ortho-substituted acetophenones and 2-acetylthiophene gave no condensation product. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Synthetic Route of C24H15Br3).

3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Synthetic Route of C24H15Br3

Density functional theory study of the substituent effect on the structure, conformation and vibrational spectra in halosubstituted anilines was written by Haruna, Kabiru;Alenaizan, Asem A.;Al-Saadi, Abdulaziz A.. And the article was included in RSC Advances in 2016.COA of Formula: C6H5Br2N This article mentions the following:

A comparative d. functional theory (DFT) study exploring the structural and spectroscopic properties of the complete set of halosubstituted anilines with the halogens being F, Cl and Br was carried out. This study aims at understanding the effect of the type, number and positions of halogen substituents on the inversion barrier, geometrical properties and vibrational frequencies. The compounds were exclusively predicted to exist in the near-planar pyramidal form. While the order of stability is noted to be independent of the type of halogen substituents, the size of the inversion barrier is predicted to be sensitive to their number and positions, in accordance with former theor. and exptl. reports. The higher number of halogens leads to a more pronounced planarity character of the amino group. The deactivating nature of halogen atoms is believed to enhance the lone-pair electron delocalization in the order of bromo- > chloro- > fluoroanilines. An unusually strong electron delocalization nature is predicted to exist in the case of tetra- and penta-substituted haloanilines. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4COA of Formula: C6H5Br2N).

3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon鑱砨romine bond is electrophilic in nature. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.COA of Formula: C6H5Br2N

Modular solid-phase synthetic approach to optimize structural and electronic properties of oligo-boronic acid receptors and sensors for the aqueous recognition of oligosaccharides was written by Stones, Duane;Manku, Sukhdev;Lu, Xiaosong;Hall, Dennis G.. And the article was included in Chemistry – A European Journal in 2004.Synthetic Route of C12H16BBrO2 This article mentions the following:

This article describes the design and optimization of the first entirely modular, parallel solid-phase synthetic approach for the generation of well-defined polyamine oligo-boronic acid receptors and fluorescence sensors for complex oligosaccharides. The synthetic approach allows an effective building of the receptor polyamine backbone, followed by the controlled diversification of the amine benzylic side chains. This approach enabled the testing, in a modular fashion, of the effect of different aryl-boronic acid units substituted with un-encumbering para electron-withdrawing or electron-donating groups. The feasibility of this approach toward automated synthesis was also investigated with the assembly of a sub-library of receptors by means of the Irori MiniKan technol. Several sub-libraries of anthracene-capped sensors containing two or three aryl-boronic acids were synthesized, and their binding to a series of model disaccharides was examined in neutral aqueous media. The calculation of association constants by fluorescence titrations confirmed that subtle changes in the structures of the inter-amine spacers in the polyamine backbone can have a significant effect on the stability of the resulting complexes. Most importantly, this study led to the determination of the preferred electronic characteristics for the aryl-boronate units, and suggests that a new generation of receptors containing very electron-poor aryl-boronic acids could lead to a significant improvement of binding affinities. In the experiment, the researchers used many compounds, for example, 2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1Synthetic Route of C12H16BBrO2).

2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Synthetic Route of C12H16BBrO2

And the article was included in Chemical Papers in 2020.Related Products of 22426-14-8 This article mentions the following:

It is extremely necessary to detect heavy metals sensitively and selectively, especially the ions that will cause great harm to humans and the environment. This work deals with two fluorescent chemosensors and their outstanding role when detecting Zn²⁺ and Cd²⁺ ions. First, a small mol. chemosensor (TPB) has been designed and synthesized via Suzuki reaction using one part of benzene-1,3,5-triyltriboronic acid and three parts of 2-bromo-1, 10-phenanthroline as starting materials. And then, its corresponding macromol. fluorescent chemosensor (PTPB) was synthesized. The IR spectra, mass spectrometry (MS), and ¹H-NMR were used to study the structures of TPB and PTPB. From what has been studied, the TPB and PTPB were stable in a relative wide pH range. As soon as the Cd²⁺ and Zn²⁺ ions added, fluorescence of the two sensors TPB and PTPB was changed obviously. In addition, PTPB was found have better performance to both Cd²⁺ and Zn²⁺ than TPB through the ”mol. wire” mechanism. Job’s plots were also be tested, showing that the combination ratio of TPB and PTPB to Cd²⁺ and Zn²⁺ were both 3:1 (ion/sensor). In addition, the min. detection limits of the macromol. chemosensor PTPB for Cd²⁺ and Zn²⁺ reached 0.424娓璏 and 1.27娓璏, resp.

Synthesis and Electrochemical Properties of Donor-Acceptor-Conjugated Polymers Based on Carbazole-EDOT Derivatives with Different Electron-Withdrawing Groups was written by Liu, Junlei;Hou, Weiwei;Xu, Ruoteng;Gao, Yijing;Xu, Lintie;Jiang, Linxiang;Zhang, Cheng. And the article was included in ACS Applied Polymer Materials in 2022.Application In Synthesis of 1-Bromopyrrolidine-2,5-dione This article mentions the following:

A series of donor (D)-acceptor (A)-conjugated monomers (ECzE-NB and ECzE-AQ) were designed and synthesized by EDOT-carbazole-EDOT (ECzE) acting as a donor (D) and anthraquinone (AQ) and nitrobenzene (NB) acting as acceptors (A) in this study. The corresponding polymer films (PECzE, PECzE-NB, and PECzE-AQ) were obtained by electrochem. polymerization, and then the effects of different acceptors on the structure and electrochem. performance of the polymers were studied. Through NMR, mass spectrometry (MS), and Fourier transform IR spectroscopy (FT-IR), it was proved that the monomers were successfully synthesized. The results of the electrochem. performance test illustrated that the electrochem. behavior of PECzE was a typical nondiffusion-controlled process. When the c.d. was 0.1 mA/cm², the specific capacity of PECzE was 8.41 mF/cm² with a rather good rate performance. However, the electrochem. behaviors of PECzE-NB and PECzE-AQ were different from that of PECzE owing to the ability of hole injection and spatial structures of the monomers changed by introducing electron-withdrawing groups.
