Deep-blue emissive and colourless polyimides: optical property tuning by triphenylamino and carbazole chromophores

Abstract

Two novel emissive chromophores based on triphenylamine and carbazole have been designed, prepared and further utilized as comonomers towards end-capped emissive colourless polyimides. The polyimide films were fabricated using 1,2,4,5-cyclohexanetetracarboxylicdianhydride/2,2-bis[4-(4-aminophenoxy)phenyl]propane...
