SYNTHESIS AND CHARACTERIZATION OF LUMINESCENT POLYHYDROXYPYRIDINE LINKED WITH AROMATIC OXADIAZOLE.

A new copoly(hydroxypyridine-oxadiazole) linked with 2,5-dialkoxybenzene group was prepared via simple polycondensation reaction. The polymer 4 is basically an amorphous material with thermal decomposition temperature greater than 250°C. Introduction of ethylhexyloxy groups into the rigid backbone resulted in better solubility in common organic solvents such as THF, chloroform, and DMF. UV-visible and fluorescence spectrometers were employed to investigate the optical properties both in solution and in the film state showing that the material has blue fluorescence.
