Spin dynamics in iodine-doped samples of a poly(thiophene) derivative, poly(3-butylthiophene-2, 5-dyle) (P3BT), was studied by temperature-dependent electron paramagnetic resonance (EPR) measurements. As a result, a change of behavior in the polaron spin-spin correlation was markedly identified in a heavily doped system.
