摘　　要：采用水热和溶剂热方法合成了2个Cu(Ⅱ)配合物:[Cu(C3H2O4)(phen)(H2O)]2·3H2O(1)和[Cu(inic)2(H2O)3]·H2O(2)(phen=邻菲啰啉;inic=异烟酸根).通过单晶X射线衍射、IR、UV-Vis-NIR吸收光谱、表面光电压光谱(SPS)对其进行了结构表征和物性测试.结构分析表明,2种配合物均为单核Cu(Ⅱ)配合物.配合物(1)中Cu(Ⅱ)离子为五配位,配位环境为畸变的四方锥构型;配合物(2)中Cu(Ⅱ)离子为五配位,配位微环境为畸变的四方锥构型.丰富的分子间氢键将它们网联成了2D配位超分子.2种配合物的SPS在300～800nm范围内都呈现出正的表面光伏响应,表明它们都具有一定的光电转换能力.分析讨论了2种配合物的电子光谱和SPS谱.Two complexes[Cu（C3H2O4）（phen）（H2O）]2·3H2O（1） and [Cu（inic）2（H2O）3]·H2O（2）had been synthesized by hydrothermal and solvothermal methods,their structures were deter- mined by X-ray single crystal diffraction. The complexes were characterized by IR, UV-Vis-NIR ab- sorption spectrum,surface photovoltage spectroscopy （SPS）. The structural analyses indicate that the two Cu （ Ⅱ） complexes are mononuclear complexes,which are networked by intermolecular hydrogen bonds into coordination supramoleculars with 2D structure. The results of SPS indicate that the com- plexes （1） and （2） exhibit positive surface photovoltage responses in the range of 300-800 nm, which shows that they have certain photo-electric conversion ability.
