Name: Tris(4-bromophenyl)amineIn 2021 ,《Spacer group-controlled luminescence and response of C3-symmetric triphenylamine derivatives towards force stimuli》 was published in CrystEngComm. The article was written by Han, Yanning; Zhang, Tong; Chen, Xinyu; Chen, Qiao; Xue, Pengchong. The article contains the following contents:

Two C3-sym. triphenylamine derivatives with three terminal cyano units as electron acceptors were prepared to investigate the effect of the spacer group on their photophys. properties and responses towards force. Their electronic transitions were carefully studied by electrochem., solvent-dependent spectroscopy and quantum chem. calculations The results suggested that introducing a double bond between the donor and acceptor results in the longer absorption and emission wavelengths of TPAVCN owing to elevated HOMO and lowered LUMO energy levels and induces a larger excited state dipole moment because of the extended conjugated length. In polar solvents, both TPACN and TPAVCN possessed a longer emission wavelength. Theor. calculations suggested that bathochromic shifts in emission bands could be ascribed to the large polar excited states owing to the light excitation-induced intramol. charge transfer. Moreover, TPAVCN had a larger charge transfer length and average degree of the spatial extension of hole and electron distribution because of its longer mol. length. In crystals, TPAVCN had a longer emission wavelength relative to that of TPACN. Moreover, both compounds could reversibly change their fluorescence under force and solvent annealing stimuli, and their mechanochromic properties were regulated by spacer groups. TPACN changed its fluorescence from blue to cyan with a spectral shift of 12 nm after grinding, but a large spectral shift of 30 nm, and an obvious fluorescent color change from green to yellow were observed while grinding pristine TPAVCN solids.

Liu, Kang; Jiao, Shaoshao; Zhao, Huihui; Cao, Fan; Ma, Dingxuan published an article in 2021. The article was titled 《Hybridization of MOFs and ionic POFs: a new strategy for the construction of bifunctional catalysts for CO2 cycloaddition》, and you may find the article in Green Chemistry.COA of Formula: C18H12Br3N The information in the text is summarized as follows:

A new strategy toward constructing a bifunctional catalyst for CO2 cycloaddition has been developed based on post-synthetic modification of CUS-based metal-organic frameworks (MOFs) with ionic porous organic frameworks (POFs) to form MOF@iPOF core-shell hybrid materials. Based on this strategy, two new MOF@iPOF core-shell hybrid materials, Cu3(BTC)2@iPOF-TB-Br- and Cu3(BTC)2@iPOF-TM-Br-, are synthesized for the first time by feasible encapsulation of a Cu3(BTC)2 core within an ionic POF shell. Because of the synergetic role of dual functional sites including CUS as a Lewis acid in the MOFs and the Br- anion as the nucleophile in the ionic POFs, Cu3(BTC)2@iPOF-TB-Br- and Cu3(BTC)2@iPOF-TM-Br- demonstrate excellent catalytic performance for the CO2 cycloaddition under co-catalyst free mild conditions (60°C, 0.5 MPa CO2, 24 h). Moreover, these core-shell bifunctional catalysts can not only realize the synergy of two functional sites, but also maintain the porosity of hybrid materials for improving the mass transfer rate and catalytic efficiency. In the experiment, the researchers used Tris(4-bromophenyl)amine(cas: 4316-58-9COA of Formula: C18H12Br3N)

The article was titled 《Self-assembled flexible metallo-supramolecular film based on Fe(II) ion and triphenylamine-subsituted alkyl terpyridine towards electrochromic application》, and you may find the article in Dyes and Pigments.Application In Synthesis of Tris(4-bromophenyl)amine The information in the text is summarized as follows:

A new metallo-supramol. film was prepared by a liquid-liquid interface self-assembly method based on the metal ion Fe(II) in water solution and a star-shaped ligand of triphenylamine-substituted alkyl terpyridine in organic solvents. The film obtained exhibited excellent flexibility due to the presence of flexible alkyl arms, and could tightly adhere to the surface of ITO glass with very smooth surface morphol. via SEM characterization. Spectroelectrochem. experiments demonstrated that the film displayed the electrochromism with purplish color in the neutralized state at 0 V vs Ag/AgCl turning to yellow-green color in the oxidized state at 1.2 V vs Ag/AgCl. This work further indicates that the liquid-liquid interfaciad self-assembly method is a promising strategy to prepare the metallo-supramol. film towards electrochromic applications.

《Rational synthesis of interpenetrated 3D covalent organic frameworks for asymmetric photocatalysis》 was published in Chemical Science in 2020. These research results belong to Kang, Xing; Wu, Xiaowei; Han, Xing; Yuan, Chen; Liu, Yan; Cui, Yong. COA of Formula: C18H12Br3N The article mentions the following:

A pair of twofold interpenetrated 3D COFs adopting a rare (3,4)-connected ffc topol. for photocatalytic asym. reactions by imine condensation of rectangular and trigonal building blocks was reported. Both COFs containing a photoredox triphenylamine moiety were efficient photocatalysts for the cross-dehydrogenative coupling reactions and asym. α-alkylation of aldehydes integrated with a chiral imidazolidinone catalyst. Under visible-light irradiation, the targeted chiral products were produced in satisfactory yields with up to 94% enantiomeric excess, which were comparable to those of reported reactions using mol. metal complexes or organic dyes as photosensitizers. Whereas the COFs became amorphous after catalysis, they were recrystallized through solvent-assisted linker exchange and reused without performance loss. This was the first reported by utilizing COFs as photocatalysts to promote enantioselective photochem. reactions.

《Toward a two-dimensional supramolecular organic framework with high degree of internal order via amphiphilic modification》 was written by Yin, Zhi-Jian; Jiang, Shu-Yan; Liu, Na; Qi, Qiao-Yan; Wu, Zong-Quan; Zhan, Tian-Guang; Zhao, Xin. Electric Literature of C18H12Br3NThis research focused ontwo dimensional supramol organic framework amphiphilic modification. The article conveys some information:

Solution-phase self-assembly of two-dimensional (2D) networks with a high degree of internal order and long-range periodicity is a great challenge. Herein, we report a rational design to improve 2D self-assembly in water through amphiphilic modification of the building block. An amphiphilic tritopic mol. (1) is designed and synthesized by introducing three hydrophilic oligo(ethylene glycol) moieties and three hydrophobic hexyl chains. The assembly of 1 and cucurbit[8]uril (CB[8]) leads to the formation of a Janus 2D supramol. organic framework (SOF), which further creates unique bilayer supramol. networks and exhibits an unprecedentedly high degree of internal order and long-range periodicity. In contrast, the assembly of a nonamphiphilic analog (2) with CB[8] only generates a 2D SOF with a lower degree of internal order, suggesting that the inherent amphiphilicity of 1 plays a crucial role in improving its 2D self-assembly in aqueous phase.

Application of 4316-58-9 And the article was included in ChemSusChem in 2020. The article conveys some information:

Developing cathodes that can support high charge-discharge rates would improve the power d. of lithium-ion batteries. Herein, the development of high-power cathodes without sacrificing energy d. is reported. N,N’-diphenylphenazine was identified as a promising charge-storage center by electrochem. studies due to its reversible, fast electron transfer at high potentials. By incorporating the phenazine redox units in a cross-linked network, a high-capacity (223 mA h g-1), high-voltage (3.45 V vs. Li/Li+) cathode material was achieved. Optimized cross-linked materials are able to deliver reversible capacities as high as 220 mA h g-1 at 120 C with minimal degradation over 1000 cycles. The work presented herein highlights the fast ionic transport and rate capabilities of amorphous organic materials and demonstrates their potential as materials with high energy and power d. for next-generation elec. energy-storage technologies.

Formula: C18H12Br3NThis research focused ontriphenylamine covalent organic framework polymer fluorescence sensor mercury removal. The article conveys some information:

A novel covalent organic framework (COF) polymer has been designed and synthesized by Suzuki polymerization of two monomers based on triarylamine derivatives, and the polymer displays nanosphere morphol. due to mini-emulsion reaction system. On the basis of the above polymer, we further fabricated a Schiff base covalent organic framework polymer fluorescent sensor for efficient detection and removal of mercury(II) ions. The material underwent a fluorescence and color change upon the touching of mercury(II) ions. Thus, taking advantage of the material to detect the presence of mercury(II) ions is quite convenient. Furthermore, the material is capable of efficiently adsorbing mercury(II) ions from aqueous solution The fluorescence sensing device was successfully fabricated by immobilizing the polymer probe on a macroporous sponge, which was more convenient to detect and remove mercury(II) ions relative to powdery polymer probe. The results came from multiple reactions, including the reaction of Tris(4-bromophenyl)amine(cas: 4316-58-9Formula: C18H12Br3N)
