Abstract
The photophysical and complexing properties of two chromo- and fluoroi onophores derived from the monoaza-15-crown-5 and styrylbenzodiazinone s are studied by UV spectrophotometry and spectrofluorometry. Their co mparison with those of BOZ-crown and DCM-crown analogous dyes shows th e specificity of the benzodiazinone moiety on these properties. The oc currence of twisted intramolecular charge transfer states by internal rotation around the ArC-N bond and the effects of biological metallic ions are discussed.
