Abstract:

A series of 3D lanthanide metal-organic frameworks(MOFs) with similar structure, [Ln(BTMC)(DMF)]·2.5DMF·3H2O[Ln=La(1), Ce(2), Pr(3), Nd(4), H3BTMC=N,N',N″-tris(4-carboxyphenyl)-1,3,5-benzenetricarboxamide], has been synthesized under solvothermal conditions. The structures and thermal-stable properties of the four compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction(PXRD), Fourier transform infrared(FTIR) spectra and thermal gravimetric(TG) analyses. The capacities of the compounds for capturing metal ions and dyes were investigated by solid state fluorescence spectra carefully, which indicated that after capturing different metal ions the emission peaks of the four compounds were blue-shift and exhibited a high Cr3+-specific luminescence enhancement.

Key words: Lanthanide metal-organic framework, Solid state fluorescence, Metal ion recognition
