含噻吩杂环 Schiff 碱及其配合物的合成与发光性质

摘要

在热乙醇中合成了2-乙酰基噻吩缩异烟酰肼及其与 Cd(II)、Cu(II)和 Zn(II)形成的三种配合物；利用元素分析、摩尔电导测定，以及红外光谱、紫外光谱和热分析确定了合成产物的组成和结构，并测定了配合物的组成及发光性质。结果表明，酰肼的配位方式的不同导致配合物呈现不同的发光性质。%2-acetylthiophene-N-isonicotinoylhydrazone and its complexes with Cd (II),Cu (II), and Zn (II)were synthesized in hot ethanol.The composition and structure of as-synthesized products were analyzed based on elemental analysis and molar conductivity measurement as well as infrared spectrometric,ultraviolet spectrometric and thermogravimetric analyses.Mo-reover,the luminescent properties of as-synthesized products were measured.Results indicate that the luminescent properties of the as-synthesized coordination compounds vary with varying coordination modes of the hydrazide.
