Abstract
New coordination zinc compounds based on 3-methyl-4-formyl-1-phenylpyrazol-5-one acylhydrazones [Zn(L)(CH3COO)Solv] (Solv is H2O (I), Py (II)) are synthesized in order to search for new luminophores demonstrating efficient photoluminescence in the visible range. Complexes I and II are characterized by elemental and thermogravimetric analyses, mass spectrometry, and UV and IR spectroscopy. The structures of two complexes [Zn(L5)(CH3COO)H2O] and [ZnL4(CH3COO)Py] are determined by X-ray structure analysis (CIF files CCDC nos. 1958400 and 1958401, respectively). Complexes I and II demonstrate luminescence in the visible range with a maximum at 414–536 nm and a quantum yield of 9.5–64% depending on the nature of the acyl fragment.
