Photophysical Properties of Composites Derived from Poly-N-Epoxypropylcarbazole and Molecules of Organic Conductors

We investigated the photoconducting and photovoltaic properties of thin film composites derived from poly-N-epoxypropylcarbazole doped with molecules of two organic conductors, namely, tetrathiafulvalene and nickel dithiolene derivatives. These compounds were found to possess hole photoconductivity. The internal photoeffect is a function of the photogeneration of the charge carriers from the additive molecules and charge transport through the donor fragments of the polymer matrix.
