Abstract

We have studied the room-temperature spin dynamics in a series of (Formula presented)-doped poly[2-buthoxy-5-methoxy phenylenevinylene] (PBMPV) conducting polymers by means of (Formula presented) NMR in the Larmor frequency range 20 to 45 MHz. The nuclear magnetization recovery of the (Formula presented)-doped (PBMPV) conducting polymers showed a stretched-exponential form, and the spin-lattice relaxation rate was inversely proportional to the square root of the (Formula presented) Larmor frequency. Our results are consistent with the one-dimensional spin diffusion of the mobile spin-carrying polarons along the main chain, and gave the intrachain diffusion constant as a function of the electrical conductivity.
