利用室温挥发方法合成了手性化合物[Cd(bbp)2(H2O)2]·bbp·2NO3·H2O(bpp=1,3-二(4-吡啶基)丙烷);利用X射线单晶衍射分析了产物的分子结构,并测定了其荧光光谱和固体圆二色光谱.结果表明,合成产物具有含一维手性链[Cd(bbp)2(H2O)2]n的手性超分子结构;其在室温下表现出中等强度的倍频效应,其二阶非线性极化率为尿素的0.4倍,是潜在的二阶非线性光学材料.此外,合成的手性化合物呈现弱的荧光,其固体圆二色光谱则呈现正的Cotton效应.
The chiral compounds [Cd (bbp) 2 (H2O) 2] · bbp · 2NO3 · H2O (bpp = 1,3-bis (4-pyridyl) propane) were synthesized by the method of volatilization at room temperature. The molecular structure of the product was determined and its fluorescence spectra and solid circular dichroism spectra were determined. The results show that the synthesized product has a chiral supramolecular structure containing one-dimensional chiral chain [Cd (bbp) 2 (H2O) 2] n. It exhibits a moderate frequency doubling effect at room temperature and its second-order nonlinear polarizability is 0.4 times that of urea, which is a potential second-order nonlinear optical material.In addition, the synthesized chiral compounds exhibit weak fluorescence, which The solid circular dichroism shows a positive Cotton effect.
