Synthesis and Copolymerization Study of New Polyimide Precursors with Potential Application in Optical and Photonic Field
摘要:
New polyimide precursors were synthesized by simple one step procedure. (Z)-3-(4-Nitro-phenylcarbamoyl)-acrylic acid (A2), (Z)-3-(4-Ciano-phenylcarbamoyl)acrylic acid (A3), (Z)-3-(4-Diethyl-phenylcarbamoyl)-acrylic acid (A4) and (Z)-3-[N'-(2,4-Dinitro-phenyl)-hydrazinocarbonyl]-acrylic acid (A6) were characterized by FT-IR, FT-NMR and UV-VIS spectroscopy. Test copolymerization successfully yielded copolymers that were characterized by FT-IR and FT-NMR spectroscopy. Improved solubility of these copolymers make them candidates for potential NLO applications.
