The article was titled 《Enhancing near-infrared AIE of photosensitizer with twisted intramolecular charge transfer characteristics via rotor effect for AIE imaging-guided photodynamic ablation of cancer cells》.COA of Formula: C18H12Br3N The article contains the following contents:

Near-IR (NIR) aggregation-induced emission (AIE) of previous organic photosensitizers is usually weak because of the competition between twisted intramol. charge transfer (TICT) effect and AIE. Herein, we report a rational mol. design strategy to boost NIR AIE of photosensitizers and still to keep strong 1O2 production capacity via rotor effect. To this end, one new triphenylamine (TPA)-based AIE photosensitizer, TPAM-1, is designed to give strong ability to generate 1O2 but weak NIR fluorescence in the aggregate state due to the strong TICT effect. Another new TPA-based AIE photosensitizer, TPAM-2, is designed by introducing three p-methoxyphenyl units as rotors into the structure of TPAM-1 to modulate the competition between AIE and TICT. TPAM-1 and TPAM-2 exhibit stronger ability to generate 1O2 in the aggregate state than the com. photosensitizer, Ce6. Furthermore, TPAM-2 gives much brighter NIR luminescence (25-times higher quantum yield) than TPAM-1 in the aggregate state due to the rotor effect. TPAM-2 with strong NIR AIE and 1O2 production capability was encapsulated by DSPE-PEG2000 to give good biocompatibility. The DSPE-PEG2000-encapsulated TPAM-2 nanoparticles show good cell imaging performance and remarkable photosensitive activity for killing HeLa cells. This work provides a new way for designing ideal photosensitizers for AIE imaging-guided photodynamic therapy.

Nath, Ipsita; Chakraborty, Jeet; Abednatanzi, Sara; Van Der Voort, Pascal published an article in 2021. The article was titled 《A ′Defective′ Conjugated Porous Poly-Azo as Dual Photocatalyst》, and you may find the article in Catalysts.Computed Properties of C18H12Br3N The information in the text is summarized as follows:

A heterogeneous photocatalyst amenable to catalyze different chem. reactions is a highly enabling and sustainable material for organic synthesis. Herein we report the synthesis and characterization of an azobenzene-based organic π-conjugated porous polymer (AzoCPP) as heterogeneous dual photocatalyst manifesting net-oxidative bromination of arenes and dehydroxylation of boronic acids to corresponding phenols. Hierarchical porosity and high surface area of the nano-sized AzoCPP allowed superior catalyst-substrate contact during catalyzes, whereas the inherent structural defect present in the CPP backbone resulted in low-energy sinks functioning as de facto catalytic sites. A combination of these two structure-property aspects of AzoCPP, in addition to the dielec. constant manipulation of the system, led to excellent catalytic performance. The protocols remained valid for a wide substrate scope and the catalyst was recycled multiple times without substantial loss in catalytic activity. With the aid of subsequent control experiments and anal. characterizations, mechanisms for each catalysis are proposed and duly corroborated. In addition to this study using Tris(4-bromophenyl)amine, there are many other studies that have used Tris(4-bromophenyl)amine(cas: 4316-58-9Computed Properties of C18H12Br3N) was used in this study.

《An Efficient Electrochromic Supercapacitor Based on Solution-Processable Nanoporous Poly{tris[4-(3,4-ethylenedioxythiophene)phenyl]amine}》 was written by Lv, Yaokang; Yang, Xing; Du, Weishi; Ma, Peihua; Wang, Hu; Bonnefont, Antoine; Wright, Dominic S.; Ruhlmann, Laurent; Zhang, Cheng. Recommanded Product: Tris(4-bromophenyl)amine And the article was included in ChemSusChem in 2020. The article conveys some information:

A new green synthetic route to tris[4-(3,4-ethylenedioxythiophene)phenyl]amine (TEPA) monomer has been developed and the mol. structure of TEPA has been determined by using single-crystal XRD. Solution-processable nanoporous poly{tris[4-(3,4-ethylenedioxythiophene)phenyl]amine} (PTEPA) is prepared by a chem. oxidative polymerization in a microemulsion. Based on the distorted structure of TEPA in the solid state, it is proposed that dendritic PTEPA has a distorted 3 D conformation with multiple twisted channels and pores that are narrowed and blocked by bifurcation and distortion of PTEPA, which is consistent with the observed hierarchical pore structure. As a cathode material, PTEPA exhibits a discharge capacity of 89.5 mAh g-1 in the initial cycle with a highly sloping two-stage discharge curve and relatively stable cycling performance. Beyond its excellent energy storage properties, PTEPA also shows relatively good electrochromic performance. Furthermore, an efficient all-solid-state electrochromic supercapacitor (ECSC) with good electrochromic performance and high energy storage capacity (13.3 mF cm-2) is assembled from PTEPA and nanoporous graphene films. During charge-discharge processes, the color of the ECSC changes between yellow-green and steel blue. Thus, the energy storage level of the ECSC can be monitored by the corresponding color changes. The fabricated ECSC may have practical applications, for example, in self-powered electrochromic smart windows.

Omar, Hanaa S.; Abd El-Rahman, Soheir N.; AlGhannam, Sheikha M.; Sedeek, Mohamed S. published an article in 2021. The article was titled 《Antifungal Evaluation and Molecular Docking Studies of Olea europaea Leaf Extract, Thymus vulgaris and Boswellia carteri Essential Oil as Prospective Fungal Inhibitor Candidates》, and you may find the article in Molecules.Product Details of 4316-58-9 The information in the text is summarized as follows:

The present study investigated the antifungal activity and mode of action of four Olea europaea leaf extracts, Thymus vulgaris essential oil (EO), and Boswellia carteri EO against Fusarium oxysporum. Fusarium oxysporum Lactucae was detected with the internal transcribed spacer (ITS) region. The chem. compositions of chloroform and dichloromethane extracts of O. europaea leaves and T. vulgaris EO were analyzed using GC-MS anal. In addition, a mol. docking anal. was used to identify the expected ligands of these extracts against eleven F. oxysporum proteins. The nucleotide sequence of the F. oxysporum Lactucae isolate was deposited in GenBank with Accession NumberMT249304.1. The T. vulgaris EO, chloroform, dichloromethane and ethanol efficiently inhibited the growth at concentrations of 75.5 and 37.75 mg/mL, whereas Et acetate, and B. carteri EO did not exhibit antifungal activity. The GC-MS anal. revealed that the major and most vital compounds of the T. vulgaris EO, chloroform, and dichloromethane were thymol, carvacrol, tetratriacontane, and palmitic acid. Moreover, mol. modeling revealed the activity of these compounds against F. oxysporum. Chloroform, dichloromethane and ethanol, olive leaf extract, and T. vulgaris EO showed a strong effect against F. oxysporum. Consequently, this represents an appropriate natural source of biol. compounds for use in healthcare. In addition, homol. modeling and docking anal. are the best analyses for clarifying the mechanisms of antifungal activity.

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.

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.

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.

《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.
