Multi-Color Fluorescence of Copolymer of Diphenylamine and M-Chloroaniline and their Hybrids with TiO2 and ZnO

2015

Vivek Kumar Singh Ram Adhar Singh

Poly(m-chloroaniline) (3clp), polydiphenylamine (dpa), copolymer of diphenylamine and mchloroaniline (3clpdpa), composite of copolymer with TiO2 (3clpdpat), and composite of copolymer with ZnO (3clpdpaz) have been chemically prepared by oxidative polymerization of polymer and copolymer with TiO2, ZnO. These were characterized by FTIR, UV–visible, Fluorescence spectra, Atomic force microscopy an...

DFT computations have been performed to gain insight into the mechanisms of formylation/methylation of amines (e.g. methylaniline (1a)/2,2,4,4-tetramethylpiperidine (2a)) with CO2 and hydrosilane ([Si]H2, [Si] 1⁄4 Ph2Si), catalyzed by 1,3,2-diazaphospholene ([NHP]H). Different from the generally proposed sequential mechanism for the methylation of amine with CO2, i.e. methylation proceeds via f...
