混合配体构筑的钌-铀酰异金属配位聚合物的合成和晶体结构及荧光性能
SYNTHESIS,CRYSTAL STRUCTURE AND FLUORESCENCE PROPERTY OF RU-U HETEROMETALLIC COORDINATION POLYMER CONSTRUCTED BY MIXED LIGANDS
摘要
Abstract
A new heterometallic organic coordination polymer,i.e.[Ru(bipy)3][(UO2)2(BDC)3]·2H2O was synthesized by the reaction of ruthenium metal complex ion([Ru(bipy)3]2+)and aromatic organic dicarboxylic acid ligand(benzene-1,4-dicarboxylate acid,H2BDC)with uranyl ion under hydrothermal condition.The structure of the coordination polymer was characterized with single crystal X-ray diffraction,powder X-ray diffraction and infrared spectroscopy.Under the[Ru(bipy)3]2+ templates,the complex formed a two-dimensional honeycomb structure with[(UO2)2(BDC)3]2-planar noninterpenetrated honeycomb layer.Intra-and inter-layer hydrogen bonding between the two dimensional honeycomb structure and guest cations contributed to the stabilization of the overall framework.This double layer was eventually connected into a quasi-three dimensional(3D)network.In addition,the solid state UV-Vis diffuse reflectance spectroscopy showed that the complex had semiconductor properties and was a potential photoelectric material.The solid state fluorescence measurement shows that the title complex exhibits strong luminescence.关键词
