Abstract Objective: Synthesis of a series of methylene-imidazolones with complexing groups. Methods: The formation of imines with the following [2+3]-cycloaddition and recycling. The use of phosphazene to form an acyclicanalogue. The optical properties were studied with and without ions of metals. The spectrofluorimetric titration was carried out to evaluate the binding constants. Results and Discussion:
