Triphenylamine (TPA) derivatives have attracted considerable attention because of their electroactive properties and potential applications as hole transporters, light emitters and photoconductors. Therefore, a study of the electrochemical process of TPA-based materials is a very important category. Aromatic polyimides (PIs) have excellent thermal stability, dimensional stability, and mechanical properties. Commonly, PIs are prepared using dianhydride and diamine monomers in a polar aprotic solventto synthesize poly(amic acid), which is a precursor of PI. The PAA precursor obtained is then converted to PI by thermal imidization or chemical imidization. In this study, PAAs were prepared using different TPA derivatives with various TPA moiety, with a dianhydride monomer in NMP. The Ps were then synthesized by the chemical imidization of PAAs solutions. |
