摘要
研究合成配合物Co(Hdpa)3(C lO4)2(Hdpa=2,2′-二吡啶胺),并测定配合物在甲醇、甲苯、乙醇、乙腈、N,N-二甲基甲酰胺和二甲亚砜等6种溶剂中的紫外光谱和荧光光谱性质.结果表明,配合物的电子吸收光谱和发射光谱的最大峰位置与强度在不同溶剂中有很大差异,主要是由各种溶剂的极性(介电常数)和施主性质(施主数)不同引起的.
A cobalt( Ⅱ )complex of Co(Hdpa)3 (ClO4)2 is synthesized. The spectral properties of the complex Co (Hdpa) 3 ( ClO4 ) 2 in six kinds of solvents ( methanol, toluene, ethanol, ethanenitrile, N, N - dimethyl formamide and DMSO) are studied by absorption spectrum and fluorescence spectrum. The wavelength and the intensity of the absorption and emission of the complex in solvents depend on the electric constant and donor number of the solvents.
