Abstract

In this work, electron-transporting chromophores were introduced to emission polymer to increase its electron affinity. Several emission chromophores also were synthesized to polycondensate with electron transporting chromophores. The influence of structure on optoelectric properties was investigated in detail. 2,5-Bis-(4- fluorophenyl)-1,3,4-oxadiazole and 9,10-dihydro-oxa-10- phosphaphenanthrene-10-oxide (DOPO) derivatives were used as electron transport and emission monomers, respectively. The DOPO derivatives that contain benzene, biphenylene or 1,4- naphthalene were synthesized. The emission units exhibits blue light as expected. Aromatic polyethers were obtained by nucleophilic displacement reaction of oxadiazole-activated bis(halide) monomers with bis(phenol) monomers. All the resulted polymers are thermally stable below 400 degrees C. The absorption peaks of these polymers vary between 325 nm - 350 nm, while the photoluminescence peaks vary between are 377 nm - 464 nm.
