Synthesis, structure, and spectral studies of zinc and cadmium complexes with 2-tosylaminobenzaldehyde and aminoquinoline azomethine derivatives

摘要

New zinc and cadmium complexes with 3-[2-(N-tosylaminobenzylidene)]aminoquinoline (HL1) and 6-[2-(N-tosylaminobenzylidene)]aminoquinoline (HL2) were synthesized. The structures of HL1, HL2 and complexes ML2 (M = Zn, Cd) were established based on the elemental analysis data, IR spectroscopy, H-1 NMR spectroscopy, and quantum chemical calculations. Electron absorption and photoluminescence spectra of the complexes were studied. OLED devices were developed, where ZnL2 (2) complexes were used as an emission layer. This device emitted yellow light with CIE x = 0.436, y = 0.492 and x = 0.463, y = 0.484, maximum luminance at 10 V was 126 and 150 cd m(-2), respectively.
