NLO polymers NLOPS based on the polyp-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.
