Abstract
Magnetic, relaxation, and dynamic parameters of polarons P1 ·+, trapped in p-toluenesulfonic aciddoped polyaniline, polarons P2 ·+, and fullerene radical anions photoinduced in the poly(3-dodecylthiophene)/methanofullerene composite and in mixtures of these composites have been investigated using the EPR technique. It has been shown that spin charge carriers P2 ·+ during diffusion along poly(3-dodecylthiophene) chains interact with P1 ·+ trapped on adjacent polymer chains of polyaniline. The exchange interaction and spin relaxation in the ternary composites is determined by the activated hopping mobility of polarons P2 ·+ and depends on the composition of the material.
