Abstract

Saiwai-ku, Kawasaki 210-8582, JAPAN The drift mobility and the diffusion coefficient of molecularly doped polymers (MDPs) are measured by fitting the theoretical equation to the observed time—of—flight photocurrent transient. The 70% mobility enhancement is observed when 0.2 wt.% fullerene C70 is added to the diphenylamino— benzaldehyde diphenyl hydrazone (DPH) doped polystyrene. We consider this is due to the interaction between C0 and DPH which form the charge transfer complex.

Keywords: molecularly doped polymer, diffusion, drift mobility, time—of—flight experiment.
