Synthesis and characterization of new photorefractive polymers with high glass-transition temperatures
چکیده انگلیسی

This paper reports detailed synthesis and characterization of some new high-Tg photorefractive polymers, polyphosphazene P3–P8. They were obtained via a post-azo coupling reaction. The resulting materials have been characterized by means of 1H NMR, 31P NMR, FT-IR, UV–vis, GPC and DSC. Chromophore contents up to 14 mol% have been realized. The polymers had high glass-transition temperatures and good optical transparency. Measurements reveal that they possess relatively large magnitude of photoinduced birefringence.
