一种新型配位聚合物的合成和漫反射光谱研究

Synthesis and Diffuse Reflectance Spectra Study of a Novel Coordination Polymer

采用均相法,在室温下合成配位聚合物[Co2(1,10-phen)2(1,4-tpht)2(H2O)2]n(1,10-phen=1,10-菲啉;1,4-H2tpht=1,4-对苯二甲酸).热分析(TGA)表明该晶体在温度低于190℃时是稳定的.UV-Vis-NIR(紫外-可见-近红外)漫反射光谱对该晶体的测定结果表明,该晶体的能隙值为2.4e V,属于半导体材料.对均相法反应的影响因素如溶剂类型、溶液的浓度以及溶液的混合速度进行了系统研究.

A novel coordination polymer [CO2（phen）2（1,4-tpht）2（H2O）2]n（1,10-phen=1,10-phenanthroline;1,4-H2tpht=1,4-benzenedicarboxylic acid） was synthesized at room temperature. The result of TGA indicates that the title compound is stable under 190℃. The title compound is semiconductor with the energy gap of 2.4 eV. And the effects of reaction conditions were discussed.
