Synthesis and electrochromic property of polyamines containing 4,4’-diaminotriphenylamine-N,N’-diyl unit in the polymer backbone: Ru-catalyzed N–H insertion polycondensation of 1,4-phenylenebis(diazoacetate) with 4,4’-diaminotriphenylamine derivatives

A new type of polyamine containing 4,4’-diaminotriphenylamine-N,N’-diyl unit in the main chain was prepared by Ru-catalyzed polycondensation of a bis(diazocarbonyl) compound with 4,4’-diaminotriphenylamine, where the propagation is N–H insertion of...
