Synthesis and characterization of poly(aryl ether imide)s containing electroactive perylene diimide and naphthalene diimide units

The synthesis and polymerization of two new electroactive bisphenols derived from 3,4,9,10-perylenetetracarboxylic dianhydride and 1,4,5,8-naphthalenetetracarboxylic dianhydride with 2-(4-aminophenyl)-2-(4-hydroxyphenyl)propane, respectively, are described. Copolymerization using the two new bisphenols and 4,4′-isopropylidenediphenol with bis(4-fluorophenyl)sulfone and 4,4′-difluorobenzophenone, afforded a series of soluble electrochromic poly(aryl ether imide)s with glass-transition temperatures ranging from 160 to 315 °C.
