Abstract

A novel cadmium coordination polymer, namely, {[Cd(Htcpb)(DMF)(H2O)2]·1.5H2O}n(1) has been hydrothermally synthesized from Cd(NO3)2·4H2O and a flexible triangle ligand of 1,3,5-tris(4-carboxyphenoxy)benzene (H3tcpb). The structure has been determined by single-crystal X-ray diffraction analysis, elemental analysis, IR spectrum, powder X-ray diffraction, and thermanalysis. The structural analysis displays that complex 1 obtained at 120 °C features a 1D chain containing mononuclear cadmium centers. The fluorescence property of complex 1 was examined in the solid-state at room temperature, and upon excitation at 290 nm, it exhibits distinct fluorescence with the maximum emission at 389 nm.

摘要

一种新型的镉配位聚合物{[Cd(Htcpb)(DMF)(H 2 O)2 ]·1.5H 2 O} n1)由Cd(NO 32 ·4H 2 O和1,3,5-三(4-羧苯氧基)苯的柔性三角配体(H 3 tcpb)。通过单晶X射线衍射分析,元素分析,IR光谱,粉末X射线衍射和热分析来确定结构。结构分析表明,在120°C下获得的配合物1具有包含单核镉中心的1D链。配合物1的荧光性质 在室温下在固态下进行检测,在290 nm激发后,它显示出明显的荧光,并在389 nm处具有最大发射。
