摘要
以三角柔性1,3,5-三(4-羧酸苯氧基)苯(H3TCPB)为配体,在溶剂热条件下合成了一个结构新颖的二维镁金属有机骨架化合物[Mg1.5(TCPB)(DMF)(H2O)]·DMF(1),通过单晶X-射线衍射,红外光谱,元素分析,粉末X-射线衍射和热重分析对其结构进行了表征.单晶X-射线衍射分析表明:配合物1属于三斜晶系,P-1空间群,为三核镁簇和3-连接TCPB3配体所构建的二维层状结构.此外,在室温条件下研究了固态配合物1的荧光性质.研究表明:配合物1所产生的的蓝紫色荧光来源于配体内部π←π*电子跃迁.
Abstract
A novel two-dimensional magnesium metal-organic framework,namely[Mg1.5(TCPB)(DMF)(H2 O)]·DMF(1),which has been prepared via the solvothermal method based on triangle flexible 1,3,5-tri(4-carboxyphenoxy)benzene ligand(H3 TCPB),and characterized by single crystal X-ray diffraction,IR spectra,elemental analysis,powder X-ray diffraction(PXRD)and thermogravimetric analysis(TGA).The single crystal X-ray diffraction analysis reveals that complex 1 crystallizes in triclinic space group P-1 and exhibits two-dimensional layered framework constructed by trinuclear Mg SBUs and 3-connected TCPB3-linker.In addition,the solid state luminescent property of complex 1 was also investigated at room temperature.It emits blue-purple fluorescence which is attributed to the intraligand π← π* transition.
