ABSTRACTWe report the synthesis and characterization of a novel series of aryl-substituted PPVs, which have shown excellent processability, good thermal stability, high photoluminescence quantum efficiency and low content of structural defects. The substituents of the polymers were designed with different degree of hindrance effect on the main chain. 1H NMR measurement indicates that the defect structure in the polymer main chain can be effectively depressed by introducing bulk and hindrance substituents.

Good Thermal Stability

Polysulfonyldiphenylene phenylphosphonate (PSPPP) with high melting range of 197 to 205 °C was synthesized via molten polycondensation method. The effect of material ratio, reaction temperature and reaction time of the method was studied, and the preferred reaction conditions were obtained. The target product was characterized by FTIR and thermogravimetric analysis (TGA) was carried out to confirm the thermal stability. The PSPPP synthesized in this paper showed fairly good thermal stability.

General Method

A general method for the preparation of amide-containing aromatic polyether ketones has been developed. Polymerization is based on a ketone-activated halo displacement in amide-containing bis(4-fluorobenzoyl) moieties by phenoxides. N,N-Bis[4-(4-fluorobenzoyl)-(4-phenoxyphenylJ]terephthalamide and 4-[(4-fiuorobenzoyl)-(4-phenoxyphenylcarbamoyl)]-N-[(4-fluorobenzoyl)-(4-phenoxyphenyl)]phthalimide were prepared by reaction of 4-fluoro-benzoyl chloride with N,N.bis(4-phenoxyphenyl)terephthalamide and 4-(4.phenoxy-phenylcarbamoyl)-N-(4-phenoxyphenyl)phthalimide, respectively, in dichloromethane in the presence of aluminum chloride. Reaction of N,N-bis[4-(4-fluorobenzoyl)-(4-phenoxyphenyl)]-terephthalamide and 4-[(4-fluorobenzoyl(4-phenoxyphenylcarbamoyl)]-N-[(4-fluorobenzoyl)-(4-phenoxyphenyl)]phthalimide with diphenols in an aprotic solvent in the presence of potassium carbonate gave a series of aromatic poly(ether ketone amide)s. Films of the aromatic poly(ether ketone amide)s displayed good thermal stability, flexibility, and T, values ranging from 134 to 186 CC. The dielectric constants of the films were characterized as a function of relative humidity (RH).
