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.

3-甲基-4-甲酰基-1-苯基吡唑-5-酮酰基hydr与配位锌化合物的光致发光

摘要

基于3-甲基-4-甲酰基-1-苯基吡唑-5-酮酰基hydr [Zn（L）（CH ₃ COO）Solv]（溶剂为H ₂ O（I），Py（II））的新型配位锌化合物为为了寻找在可见光范围内能有效发光的新型发光体进行了合成。配合物I和II的特征在于元素分析和热重分析，质谱以及UV和IR光谱。两种配合物[Zn（L ⁵）（CH ₃ COO）H ₂ O]和[ZnL ⁴（CH _{3）的结构}通过X射线结构分析（CIF文件CCDC编号1958400和1958401）确定。配合物I和II在可见光范围内发光，最大发光波长为414-536 nm，量子产率为9.5-64％（取决于酰基片段的性质）。
