Abstract

Bis{4-[bis(4-methoxyphenyl)amino]-2,6-bis(2,4,6,triisopropylphenyl) phenyl}diphosphene (1), possessing two bis(4-methoxyphenyl)amino groups as redox sites as well as electron-donating sources, was synthesized and isolated as a red solid. The cyclic voltammogram of 1 at -78° consisted of three reversible redox waves corresponding to two-step oxidation of the triarylamine moieties and reduction of the diphosphene moiety. Introduction of the two amino groups also contributed to a red shift of the absorption maximum in the UV/VIS spectrum, which was responsible for the intense red color of 1.
