showed that the subaric ligand in the two complexes exhibits two types of modes coordinating to transition metal ions, resulting in the formation of a 1D infinite chain along the c-axis. In addition, the results of SPS for complexes 1 and 2 indicate that these two complexes exhibit positive surface photovoltage responses in the range of 300–800 nm, which can be assigned to LMCT and MLCT, respectively.

二维配位聚合物,[M(C 8 H 12 O 4)(C 10 H 8 N 2)]·H 2 O [M = Co(1),Cd(2);C 10 H 8 N 2 = 4,4-联吡啶,C 8 H 14 O 4 =亚芳酸]是由金属盐,联吡啶和亚芳酸在180℃下的反应获得的,并通过元素分析,红外光谱,单晶X射线衍射和表面光电压谱(SPS)表征。X射线单晶衍射表明,两种配合物中的亚芳基配体均表现出两种与过渡金属离子配位的模式,导致沿c轴形成一维无限链。此外,复合物1和2的SPS结果表明这两种复合物在300-800 nm范围内表现出正的表面光电压响应,可以分别分配给LMCT和MLCT。和复合物1的SPS也可以分配给d→d *电子转换。两种配合物的SPS光谱与其紫外可见光谱一致。
