采用水热合成法得到了新颖结构的配位超分子[Cu(phen)(H2O)2.SO4]。通过X射线单晶衍射、红外光谱(IR)、紫外光谱(UV-VIS-NIR)及荧光光谱进行了测定和分析指认结构分析表明:标题化合物中Cu离子的配位模式分为两种,与phen分子中的2个N原子和水分子中2个O原子是通过配位键直接配位的;与硫酸根离子中的2个O原子的配位是采取Cu离子与O原子之间形成氢键,该氢键使Cu离子和硫酸根离子中的2个O原子处于亚配位状态,因此使Cu离子处于扭曲的八面体几何构型中。晶体中存在着大量的氢键将化合物连成了1D双链结构。利用表面光电压光谱(SPS)和场诱导表面光电压光谱(FISPS)研究了化合物的表面光电行为。化合物的SPS在300～800nm范围内呈现出明显的2个正的光伏响应带。FISPS的结果显示化合物呈现出一定的p-型半导体的特征。
Hydrothermal synthesis of the novel structure of the coordination supramolecular [Cu (phen) (H2O) 2.SO4]. The results of X-ray single crystal diffraction, IR, UV-VIS-NIR and fluorescence spectroscopy indicated that the coordination structure of Cu ion in the title compound was divided into two kinds, The two N atoms in the phen molecule and two O atoms in the water molecule are coordinated directly through the coordination bond. The coordination with the two O atoms in the sulfate ion takes the form of hydrogen between the Cu ion and the O atom Bond that places the two O atoms in the Cu ion and the sulfate ion in a sub-coordination state, thus leaving the Cu ion in a distorted octahedral geometry. There are a large number of hydrogen bonds in the crystal compound into a 1D double-stranded structure. The surface photovoltage behavior of the compounds was investigated by surface photovoltage spectroscopy (SPS) and field-induced surface photovoltage spectroscopy (FISPS). The SPS of compound shows obvious two positive photovoltaic response bands in the range of 300 ~ 800 nm. The results of FISPS show that the compounds exhibit certain p-type semiconductor characteristics.
