Combined polarons in a pernigraniline-base polymer
Abstract
We found a ring-torsin polaron which is associated with a bond-order polaron in a pernigraniline-base polymer on the basis of the extended Ginder-Epstein model. The calculated electronic structure for a n-type polaron has shown that the transition from the lower gap level to the higher one matched the 1.5 eV peak of photoinduced absorption in the polymer. The origin of the large defect mass is suggested.
