FIELD : chemistry. SUBSTANCE : described are 15-crown-5- and dithia-18-crown-6-containig 2-methyl-9-styryl phenanthrolines of formula : where as optical sensors on cations of calcium, barium and lead. Claimed compounds are obtained by interaction of ligand of 15-crown-5 or dithia-18-crown-6-containing 2-methyl-9-styryl phenanthroline with zinc perchlorate in acetonitrile with irradiation with red light. EFFECT : complexes possess properties of highly efficient fluorescent sensors on cations of calcium, barium and lead, which make it possible to visually determine metal cation. 2 cl, 2 tbl, 2 ex
