Three new chelate zinc complexes with azomethine groups characterized by luminescence in the visible spectral region were synthesized: bis(N (2 oxybenzylidene)cyclohexylamine)zinc, bis(N (2 oxybenzylidene) 4 tert butylaniline)zinc, and N,N´ bis(oxybenzylidene) 1,2 phe nylenediaminezinc. Their spectral properties were studied. Based on these complexes, we prepared electroluminescence devices giving an intense emission in the blue, green, and red spectral regions.
