There are provided photoconductive compounds wherein 3-substituted N-alkyl carbazole groups and 3,5-dinitrobenzoic acid moieties are attached directly or via spacer groups to a polymeric backbone. The photoconductive compounds can be used in devices based on the photoconductivity of such compounds, such as sensors or the like, said compounds being used in the form of a film or a coating. The maximum sensitivity of such sensors is in the IR region.
