摘　　要：锌配合物的绿色合成与表征是结合配合物基础知识和当前科学研究热点设计改进的一个综合性实验。本文以水为溶剂,以对氨基苯磺酸(4-ABS)和ZnO为主要原料,直接法制备得到一种三维网状配合物。对该配合物进行单晶X射线衍射、红外光谱、热重分析、紫外以及荧光光谱等结构表征,并采用Materials Studio (MS)软件的CASTEP模块,对配合物的几何构型进行优化,从原子水平上进一步佐证配合物的最优结构及稳定化能。该实验过程包含配合物制备、蒸发浓缩、减压过滤、单晶培养、紫外及荧光光谱测试、热重分析、理论计算等,整个教学过程综合性及可操作性较强。同时,该实验把绿色合成融入到实验方案设计和实施的全过程,使学生树立节能环保的理念,激发学生探究真知的兴趣和热情,使其在加深理解配位化学基础知识的同时,获得了相关前沿热点知识,对培养学生创新思维、科学研究能力和综合素质具有十分重要的意义。The green synthesis and characterization experiment of a Zn(II)complex is a comprehensive experiment that combines the basic knowledge and the scientific research frontier of the complex.In this paper,a three-dimensional complex was prepared using p-aminobenzenesulfonic acid(4-ABS)and ZnO as the main materials.The complex is characterized by single-crystal X-ray diffraction,infrared spectroscopy,thermogravimetry,UV absorption and fluorescence spectra.The configuration of the complex is optimized by the CASTEP module of Materials Studio(MS)software,which further supports the optimal structure and stabilization energy of the complex.The experimental process includes the complex preparation,evaporation concentration,decompression filtration,single crystal culture,UV absorption and fluorescence spectroscopy,thermogravimetric analysis,theoretical calculation,etc.The whole process is comprehensive and operable.Meanwhile,the experiment integrates green synthesis into the whole experimental scheme,establishing the concept of energy conservation and environmental protection.Through this experiment,students could not only understand the principles of coordination chemistry,but also learn the frontier of scientific research.Therefore,it is helpful to train the students’scientific thinking,and enhance their ability of innovation.
