Abstract
Cyanine dyes, particularly indocyanine dyes, having at least 7 carbon atoms in the polymethine chain which may possess a fused cyclopentene or cyclohexene ring in the form of a tri-iodide salt exhibit a substantial reduction in the propensity to associate compared to dyes having the identical cation but different anion. The tri-iodide salts are particularly useful as sensitizers in organic photoconductor systems.
