Silicon-containing oligomeric poly(imido-amides) (PIAs) were synthesized from dicarboxylic imido-acids containing a Si atom, which were obtained from dianhydrides, amino acids and p-aminobenzoic acid, were polymerized with the diamine bis(4-aminophenyl)diphenylsilane.
exhibit film forming ability and good solubility in many organic solvents. They show high thermal stability, with decomposition temperature being above 420 °C. The optical properties, absorption and fluorescence characteristics, in solution and solid state, are investigated. Solutions of the polymers exhibit fluorescence in the blue region, having high quantum yield in the range of 38.5–58.1%, and
