Poly[2-buthoxy-5-methoxy-1,4-phenylenevinylene] (PBMPV) conjugated polymers were synthesized and iodine-doped to controllable degrees for conductivity, and electron paramagnetic resonance (EPR) and nuclear magnetic resonance (NMR) measurements. The study provided unique and the most comprehensive evidences up to date for the polaron-bipolaron spin/charge critical dynamics in these conducting polymers. Besides, fractal and critical behaviors apparently associated with the evolution of the inhomogeneous local environments and with the charge-carrier delocalization were observed.
