【摘要】 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.更多还原

【Abstract】 Chiral coordination complex[Cd(bbp)2(H2O)2]·bbp·2NO3·H2O(bpp = 1,3-bis(4-pyridyl)propane)was synthesized by room temperature evaporation method.The molecular structure of as-synthesized product was analyzed by single-crystal X-ray diffraction,while its fluorescence spectrum and solid circular dichroism spectrum were also measured.It was found that as-synthesized coordination compound has chiral supermolecular structure containing onedimensional chiral chain of[Cd(bbp)2(H2O)2]n.Besides,the crystal of as-synthesized coordination compound possesses modest second-harmonic generation(SHG)activity,and its SHG activity is approximately 0.4times as much as that of urea,showing potential application as a second-order nonlinear optical material.Moreover,as-synthesized chiral compound shows weak fluorescence,and its solid circular dichroism spectrum is dominated by positive Cotton effect.更多还原
