Abstract: N,N′-Bis(4-diphenylaminophenyl)pyromellitimide (TPA-PMDI) was synthesized from the condensation reaction of 4-aminotriphenylamine with pyromellitic dianhydride (PMDA). The triphenylamine-diimide TPA-PMDI could be electrochemically polymerized into ambipolar, redox-active polyimide films on the electrode surface in an electrolyte solution via… read more here.
