| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系 === 100 === In this research, we successfully synthesized five kind of novel electroluminescent conjugated polymers, some of the commonly used conjugated polymers for the fabrication of organic LED, such as Polycarbazole and Polyfluorene derivative, the photoluminescence spectra were used to investigated the photophysical property.
The results showed that these material had good thermal stability with 5% weight loss temperatures above 380℃. While dissolved in THF and Toluene solution, as the amount of alkyl chain on compound was increased, which is effective to constrain the aggregation on backbone of molecular chains. Especially the derivative copolymer of Polycarbazole, Polyfluorene and biphenyl with higher steric hindrance, the characteristic peaks of the photoluminescence spectra of these electrophosphorescent materials had reduce further red-shift, contains the least degree of aggregation.
