Допирование Несопряженного Полимера Органическим Соединением С Двумя Устойчивыми Энергетическими Состояниями

Abstract

We investigate the effect of doping by a small-molecular-weight organic compound phenolphthalein of non-conjugated polymer polydiphenylenephthalide. It is known that phenolphthalein has two energetically stable states - neutral and charged, as a result of the capture of an excess electron. The morphology of polymer films surfaces observed by atomic force microscopy. Analysis of the current-voltage characteristics showed that an increase of the dopant concentration leads to an increase in conductivity. Mounted connection nontrivial fact conductivity growth and mobility of charge carriers with increasing dopant concentration. At same time, an increase in the concentration of the dopant does not lead to a significant change in the charge-carrier concentration.
