Electrodeposition of Novel Cross-Linked Poly(methacrylic acid) Functionalized Poly(9-aminofluorene) Network Films

Abstract

Four novel cross-linked network conjugated poly (methacrylic acid) functionalized poly (9-aminofluorene) films were prepared by a precursor polymer approach, i.e., poly { poly [ N - (9H-fluoren-9-yl) methacrylamide ] } (P1), poly { poly [ N - (9H-fluoren-9-yl) methacrylamide-co-methacrylic acid ] } (P3), poly { poly [ N - (9H-fluoren-9-yl) methacrylamide] -co-9-aminofluorene } (P2) and poly { poly [ N - (9H-fluoren-9-yl) methacrylamide-co-methacrylic acid ] -co-9-aminofluorene } (P4). As-prepared polymer films had good redox activity and structure stability in concentrated sulfuric acid. Fluorescence spectra indicated that the soluble cross-linked polymers were good blue light emitters and in solid state they were blue-green light emitters.
