Synthesis, Structure and Properties of Cadmium Complex with Two-photon Activity

合成了一种新的配合物Cd(DASP)_(2)(NCS)_(2)·2H_(2)O,并用红外光谱、元素分析和单晶X-射线衍射进行了表征。结构分析表明,配合物属于单斜晶系,P2_(1)/c空间群,晶胞参数a=13.5142(12)Å,b=9.0458(8)Å,c=31.187(3)Å,β=93.7820(10)°,Z=4,F(000)=1704。Cd^(2+)与两个氧原子以及两个氮原子配位,处于变形四面体的配位环境中。此外,研究了配合物的吸收光谱、单光子荧光和双光子荧光光谱。

A new complex Cd(DASP)_(2)(NCS)_(2)·2H_(2)O,has been synthesized and characterized by IR,elemental analysis and single crystal X-ray diffraction.The structural analysis shows that complex belongs to monoclinic system,space group P21/c with a=13.5142(12)Å,b=9.0458(8)Å,c=31.187(3)Å,β=93.7820(10),Z=4 and F(000)=1704.The Cd^(2+)locates in a distorted tetrahedronal environment defined by two oxygen atoms and two nitrogen atoms.In addition,the absorption spectrum,single-photon fluorescence and two-photon fluorescence spectra of complex have been studied.
