摘要
利用2-(2-吡啶基)-4-羟基喹唑啉和醋酸锌在水热法条件下合成了一个新型锌配合物[(Zn(phdq)_2·2H_2O)](1)(phdq=2-(2-吡啶基)-4-羟基喹唑啉).结构分析表明配合物1为单分子结构,结晶于单斜晶系,P-1空间群.在配合物1中存在着丰富氢键和π…π作用力,通过分子间氢键和π…π堆积作用力使得配合物1形成三维网状结构.对配合物1和配体的固体荧光研究表明配合物的荧光明显增强,其原因可能是配体与金属ZnⅡ离子配位后增加了结构中的刚性.这对于开发新型荧光材料具有一定的指导与借鉴意义.
The hydrothermal reaction between 2-（2-pyridyl）-4-hydroxy quinazoline and zinc acetate in CH3CH2OH/H2O solution synthesized a new complex [Zn（phdq）2-2H2O] （1）. X-ray diffraction analysis shows that the complex 1 is a single molecular structure, which belongs to monoclinic crystal system, P-1 space group. In complex 1, there are many hydrogen bonds between molecules, which results in a three-dimensional network structure through hydrogen bonds and π-π interaction. The solid fluorescence spectra shows that the fluorescence of complex 1 enhances greatly, which probably attributes to the rigid enhancing of the structure after the coordination between ligand and metal Zn Ⅱ ion. It provides certain guidance and reference for exploiting new fluorescent materials.
