Abstract
The application of conjugated polymers having electroactive pendant groups, such as poly(N-methyl-N'-(3-pyrrol-1 -ylpropyl)-4,4'-bipyridinium), p-Pyr- V2+-Me, and poly(N-hydrogen-N'-(3-pyrrol-1-ylpropyl)-4,4'-bipyridinium), p- Pyr-V2+-H, as active photovoltaic and photoconducting media is investigated . Photoinduced charged species are characterized using photomodulated diffe rential transmission spectroscopy and photoconductivity. The ability of usi ng such media as active layers in photovoltaic cells is demonstrated.
