✦ Synopsis

The photophysical and complexing properties of two chrome-and Auoroionophores derived from the mono=-15crown-5 and styrylbenzodiazinones are studied by UV spectrophotometry and spectrofluorometry. Their comparison with those of BOZ-crown and DChkrown analogous dyes shows the specificity of the benzodiazinone moiety on these properties. The occurrence of twisted intramolecular charge transfer states by internal rotation around the Arc-N bond and the effects of biological metallic ions are discussed.
