Poly(p-phenylene) Derivatives New High Performance Nonlinear Optical Polymers.

摘要

NLO polymers (NLOPS) based on the poly(p-phenylene) (PPP) backbone were prepared in the study. The thermal stability for the new materials is presented. The polymer displayed a Tg of 220 deg C. The TGA scan of the material indicated reasonable thermal stability to 300 deg C. A thin film of the material was supported on a glass slide and heated at 200 deg C and monitored by UV-vis spectroscopy. These experiments indicated less than 10% loss of the absorption band due to the NLO-phore (i.e. chromophore) over a period of 24 h. NonLinear optical, Polymers, Conjugated polymers, Polyphenylenes.
