Abstract
We report about a series of methylene-imidazolones with complexing groups. The fluorescent properties of these compounds were studied in various solvents as well as in the presence of different salts. We discovered that two of the synthesized substances – hydroxyquinolinidene-imidazolone and difluorobenzimidazolidene-imidazolone – can be used as selective fluorescent sensors for cadmium and zinc ions and potentially as markers for monitoring intracellular processes.
