Abstract :
Proton relaxation time T1 has been measured versus the frequency on samples of polybithiophene, poly-(dimethyl-tetrathiophene), poly-(3-hexyld13-thiophene) and on a block deuterated polystyrene - polythiophene copolymer. It is shown that the polaron motion is a quasi 1D diffusion for all polymers. Intra- and interchain diffusion coefficients are obtained. Anisotropy appears to be very high in poly-(hexyl-thiophene). The results are compared taking into account structural aspects of the compounds.
