Abstract

1-Alkyl- and 1-aryl-5, 6-benzolepidinium salts undergo cyanine condensation with 1-ethylquinolinium iodide in ethanol in the presence of basic condensation catalysts to give unsymmetrical monomethinecyanine dyes. The steric hindrance present in the molecules of these dyes is responsible for a low absorption intensity of ethanol solutions of these dyes.
