Spectral and luminescent properties of N,N'-bis(5-bromosalicylidene)-1,3-propylenediamine and its zinc complex

Resumo

Zn(II) complex with N,N'-bis(5-bromosalicylidene)-1,3-propylenediamine, which efficiently luminesce in the blue region of the visible spectrum, is synthesized for the first time. It is found that, at 293 K, azomethine and zinc complex fluoresce in both solution and the polycrystalline state. Fluorescence quantum yields of the compounds in diluted dimethylformamide and dimethylsulfoxide solutions are determined.
