摘要:

采用水热合成方法得到了3个Co-M配聚物: [CoCd(mal)2(H2O)4]n(1), [CoZn(mal)2(H2O)4]n(2) 和[Co2(mal)2(H2O)4]n(3)(mal=malonate). 通过X射线单晶衍射确定了各配聚物的结构. 3个配聚物都是由丙二酸构筑并具有2D层状结构, 通过氢键进一步将2D层网联成3D无限网络结构. 通过表面光电压谱(SPS)对3个配聚物的表面光电性能进行了重点研究, 并与其相应的UV-Vis吸收光谱进行了对比. 结果表明, 这3个配聚物在300~600 nm范围内均表现出正的光伏响应, 而且SPS和UV-Vis光谱之间具有较好的对应关系.

Abstract:

Three Co-M(M=Cd, Zn, Co) coordination polymers, [CoCd(mal)2(H2O)4]n(1), [CoZn(mal)2(H2O)4]n(2) and [Co2(mal)2(H2O)4]n(3)(mal=malonate), were synthesized by hydrothermal method and structurally characterized by X-ray single crystal diffraction. The structure analysis shows that the three coordination polymers all possess 2D layer structure constructed by mal anion bridging Co(Ⅱ) and M(Ⅱ) ions. The layers are further linked by the hydrogen bonds, producing 3D network structure. The measurement and analysis of surface photovoltage spectroscopy(SPS) and UV-Vis spectra indicate that the three polymers exhibit positive surface photovoltage responses in the range of 300—600 nm, moreover, the SPS also present a consistency with UV-Vis spectra.
