含二氮杂萘联苯结构的有机光电信息材料及相关器件研究

The recent surge in demand for photonic components that meet economic criteria as well as technical requirements in the telecom and datacom industries has opened the door for novel technologies.that enable unique function and/or unconventional high-yield manufacturing without sacrificing high performance. Advance planar polymer technologies can fit the bill in every aspect. In this.project, five new fluorinated and chlorinated phthalazinone monomers and their nine polymers have been successfully synthesized. In addition, fluorinated poly(ether imide)s were also prepared for analyzing the effect of polymer’s structure on the.refractive index. The above polymers have high solubilities in several solvents such as chloroform, tetra-chloroethane and N-methyl-2-pyrrolidone, which is suitable for multi-coating 4.processing of polymer waveguide. Attractive properties are their.high thermal stabilities. The polymer glass transition temperatures.were above 240℃, and their decomposition temperatures were high.than 450℃ detected with a heating rate of 10℃/min in a nitrogen atmosphere. The polymers have high refractive indice more than 1.58 and a low water absorption rate of 0.3%. The analyses of optical loss of polymer in the view of polymer’s structure were done.in the condition of nowhere to measure in China. The research is benefit for the further development of phthalazinone-containing polymer for optical waveguide.
