摘要:

采用常规方法合成了3种Cr(Ⅲ)配合物:[Cr(en)2ox][Cr(en)(ox)2]•2H2O (1)、[Co(NH2NHCSNH2)3][Cr(ox)3]•7H2O (2)和Cr(acac)3 (3) (en=ethylenediamine, ox=oxalic acid, acac=acetylacetone)。通过X射线单晶衍射、紫外可见吸收光谱(UV-Vis)及表面光电压光谱(SPS)对配合物进行了表征。通过SPS光谱对3种配合物的表面光电性能与其相应的UV-Vis吸收光谱进行了对比。结果表明,配合物在300~600 nm范围内均可呈现较好的光伏响应,而且测得的表面光电压光谱峰位置和紫外吸收光谱有较好的对应关系。

Abstract:

Three Cr(Ⅲ)coordination complexes [Cr(en)2ox][Cr(en)(ox)2]•2H2O (1), [Co(NH2NHCSNH2)3][Cr(ox)3]•7H2O(2), Cr(acac)3(3) were synthesized by the groovy method(en=ethylenediamine, ox=oxalic acid, acac=acetylacetone) . The crystal structures of the complexes were determined by X-ray single crystal diffraction,and the complexes were characterized by UV-Vis and surface photovoltage spectrum(SPS). Surface photovoltage performance of the three complexes were emphatically studied, and compared with their UV-Vis spectra .The results of surface photovoltage spectra of complexes 1~3 indicate that the complexes exhibit better surface photovoltage responses in a range of 300~600 nm,and the determined surface photovoltage and UV-Vis spectra present comparatively well corresponding relation.

Key words: Cr(III) coordination complex, crystal structure, UV-Vis spectrum, surface photovoltage spectrum
