Abstract: Cu(Ⅱ)Coordination Supramolecule（Cu (C9H7NO)2）was synthesized in hydrothermal method, its single crystal structure being determined with X-ray diffraction. Structure analysis indicated that the hydrogen bonds in the crystal made the complex further connected to a supramolecule possessing an 1D infinite structure. Meanwhile, the IR spectrum, UV-Vis-NIR spectrum and the surface photovoltage spectrum (SPS) of the complex were measured and assigned exhibiting positive surface photovoltage responses in the range of 300～800 nm，meanwhile the absorption peaks in UV-Vis-NIR spectrum were in agreement with the responses in SPS. Field induced surface photovoltage spectrum (FISPS) show that the SPV responses' intensity of the complex increases linearly with the increase of the external positive field and reduces with the increase of the external negative field.

摘要： 采用水热合成法合成了8-羟基喹啉铜配合物(Cu(C9H7NO)2 )。对配合物进行了单晶X射线衍射
测定,结构分析表明,分子间存在的氢键将配合物连成了1D无限结构;对配合物的紫外可见吸收光谱(UV-Vis-
NIR)及表面光电压光谱(SPS)进行了测定和分析指认,配合物的SPS在300~800nm 范围内呈现出正的表面光伏
响应(SPV),而且SPS响应带与UV-Vis-NIR 光谱的吸收峰是一一对应的;配合物的场诱导表面光电压光谱
(FISPS)中,光伏响应的强度随着外加正电场的增加而增强,随着外加负电场的增加而减弱。
