Abstract

I₂-doped poly(2-butoxy-5-methoxy-1,4-phenylenevinylene) (PBMPV) conducting polymers have been studied by pulsed NMR. With increasing degree of doping and thus the electrical conductivity, changes in the microscopic environment were reflected in the NMR measurements. The spin-lattice relaxation rate (1/T₁) generally increases with the degree of doping, suggesting that the relaxation mechanism becomes more effective with heavier doping.
