Abstract
The effect of chromophore aggregation upon the photoconductivity in the dye-sensitized Langmuir films has been examined employing three derivatives of a surface-active merocyanine with a rhodanine nucleus. The values of the lateral component Δσt and the anisotropy ratio Δσ∥/Δσ⊥ for the case with a strongly developed aggregate are found to be more than a decade larger than those for no or incomplete aggregation.
