摘要
合成了两个含蒽酰亚胺基团的新配体N-(2-(6-氨基吡啶))-9-蒽酰亚胺(L1)和N,N′-(2,6-吡啶基)-二(9-蒽酰亚胺)(L2),以及L1的铜(I)配合物[CuL1(PPh3)2](BF4)(1),并研究了它们的结构和光谱性质.理论计算表明配体L1配位前为反式构象,配合物1的晶体结构显示L1配位后发生结构扭曲呈顺式构象,羰基氧原子与铜(I)离子配位.光谱研究表明配体L1和配合物1都表现出蒽的特征吸收和发射峰.
Two new ligands, N- (6-aminopyridine-2-yl)-9-an (L^1) arid N,N'- (pyridine-2,6-yl)-bis(9-anthracenecarbonamide) (L^2), and the novel copper(Ⅰ) complex of L^1, [ CuL^1 (PPh3)2 ] (BF4) (1), have been synthesized and characterized. The crystal structures of L^2 and 1 were determined by single crystal X-ray analysis, which show that the carbonyl (C=O) group in 1 is coordinated to the copper(Ⅰ) ion through the oxygen atom. In addition, the spectroscopic properties of L^1 and 1 were studied at room temperature.
