ZINC DIMERIC COMPLEXES OF CROWN-CONTAINING STYRYL PHENANTHROLINES AS OPTICAL SENSORS ON CATIONS OF ALKALI-EARTH AND HEAVY METALS AND METHOD OF THEIR OBTAINING

摘要

FIELD: chemistry.SUBSTANCE: described are 15-crown-5- and dithia-18-crown-6-containig 2-methyl-9-styryl phenanthrolines of formula:whereas 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
