Thienyl Triarylamines. Reactivity and Spectra of Cation Radicals and Dications.
摘要:
The alpha-thienyl substituted triarylamines, bis(4-bromophenyl)-4-(2-thienyl)-phenylamine (1), (4-bromophenyl)bis-[4-(2-thienyl)phenyl]amine (2) and tris[4-(2-thienyl)phenyl]amine (3) were prepared as novel molecular systems for photoelectrical conversion. Electrochemical oxidations using solvents like hexafluoroisopropanol were performed to evaluate the stability of the corresponding cation radicals. The dimer 5,5'-{bis[4-di(4-bromophenyl)amino]phenyl}-2,2'-bithiophene (1D) was prepared by an electrochemical oxidation-reduction sequence. Chemical and electrochemical oxidations of 1D were studied and UV-VIS-NIR spectra of the neutral, cation radical and dication are reported.
