## Abstract

Five zinc(II) complexes based on N-[[2-(p-tolylsulfonylamino)-phenyl]-methyleneamino]-4R-benzamides were synthesized and characterized by elemental analysis, ESI-MS, FT-IR, 1H NMR and single-crystal X-ray analysis. Crystallographic studies reveal that the complexes have a polymer structure in the solid state. Acylhydrazones and zinc(II) complexes demonstrate effective photoluminescence in solutions and in the solid state. Preliminary studies have shown that the studied complexes can be used as emitters in OLED devices and for the bioimaging of pathogenic processes at the cellular level.
