摘要：

Electronic absorption and photoluminescence characteristics of various polythiophene derivatives have been studied. Fluorescence measurements indicate that fluorescence quantum efficiency of the ester containing polythiophene derivatives are higher than that of the alkyl containing derivatives. Among the ester group substituted polythiophenes, the longer alkyl side chain gives higher quantum efficiency. The quantum yield of the polythiophene derivatives in solution is compared with the coumarin 500 laser dye. Electronic absorption and emission peak shift to the shorter wavelength are observed with increasing temperature.
