碩士 === 國立臺灣大學 === 物理研究所 === 97 === In this study, Chlorobenzene is used for dissolving the copolymers with different molecular weight which are H-PT8ML8-F8 and L-PT8ML8-F8. Film is fabricated on ITO glass by drop casting. Time of fight technique is used to measure the vertical charge carrier mobility at different temperature in this work. Based on the experimental results, the charge carrier mobility of H-PT8ML8-F8 and L-PT8ML8-F8 are almost the same. Because the copolymer PT8ML8-F8 is assembled by polythiophene polyfluorene and the other group, the mobility of PT8ML8-F8 could be compared with polyfluorene and P3HT. The charge carrier mobility of them are very approaching. It is suitable to infer that the copolymerization does not affect the charge mobility.
