摘　　要：采用水热法合成了1种V(Ⅱ)/V(Ⅲ)混合价态的V—O配聚物[(V2+)2V3+(0.5O2)10O6.2H2O]n通过单晶X-射线衍射确定了该配聚物的分子结构.结构分析表明,该配聚物是1个完全由O原子桥连而成的具有2D结构的V—O配聚物.采用表面光电压光谱(SPS)技术研究了配聚物的表面光伏性能.结果表明配聚物在300～800nm范围内呈现出正的表面光伏响应.此外,对该配聚物的UV-Vis-NIR及IR光谱进行了测定和分析指认.A V（Ⅱ）/V（Ⅲ） mixed valences coordination polymer [（V2＋）2V3＋（0.5O2）10O6·2H2O]n has been synthesized by hydrothermal method.The structure of the polymer was determined by single crystal X-ray diffraction.The structure analysis shows that the polymer is a V-O coordination polymer with a 2D layer structure bridged by O atoms.The photo-electric property was discussed by surface photovoltage spectroscopy（SPS）.The result indicates that the polymer exhibits positive surface photovoltage responses in the range of 300~800 nm.In addition,the UV-Vis-NIR and IR spectra of the polymer were measured and analyzed.
