Chemical and Electrochemical Syntheses, Structure, and Luminescent Properties of Zinc and Cadmium Complexes with N-{2-[(E)-(4-tert-Butylphenyl)iminomethyl]phenyl}-4-methylbenzenesulfonamide

Resumo

New Zn(II) and Cd(II) complexes with N-{2-[(E)-(4-tert-butylphenyl)iminomethyl]phenyl}-4-methylbenzenesulfonamide were synthesized by chemical and electrochemical methods. The ligand and metal complexes were characterized by the methods of IR, ¹H NMR, electron absorption spectroscopy, and X-ray absorption spectroscopy and by quantum chemical calculations. Electroluminescent devices with zinc and cadmium complexes were fabricated as emitter layers, which showed radiation brightness of 460 cd/m² (15 V) with a maximum at 502 nm and 140 cd/m² (15 V) with a maximum at 535 nm, respectively.
