Synthesis,structure and luminescent property of Mg(Ⅱ)metal-organic framework based on 1,3,5-tri(4-carboxyphenoxy)benzene ligand
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.
