Abstract

Optoelectronic and optical properties of poly(3-alkylthiophene) (P3HT) diluted in polystyrene (PS) matrices were investigated by flash-photolysis time-resolved microwave conductivity (FP-TRMC) and steady-state photoabsorption spectroscopy, respectively. We examined intra- and inter-molecular charge carrier mobilities in the blend and pristine P3HT films and found the contribution of inter-molecular one is half at the maximum in the pristine film. This in turn gave information about the minimum one-dimensional intra-molecular mobility of 0.18 cm².
