Synthesis and characterization of MOFs constructed from 5-(benzimidazole-1-yl)isophthalic acid and highly selective fluorescence detection of Fe(iii) and Cr(vi) in water.

ABSTRACT: In this work, four novel metal-organic frameworks [Cd(bipa)] _n (1), {[Zn₂(bipa)₂]·2C₂H₅OH} _n (2), {[Co(bipa)]·C₂H₅OH} _n (3), {[Ni(bipa)₂]·2DMA} _n (4), (H₂bipa = 5-(benzimidazole-1-yl)isophthalic acid) were successfully synthesized under solvothermal conditions. Complexes 1-4 were characterized by powder X-ray diffraction, elemental analysis, infrared spectroscopy and thermogravimetric analysis. Interestingly, the coordination patterns and 3D network structures of complexes 1-3 are very similar, while complex 4 is relatively unique. Complexes 1-2 exhibit potential fluorescent properties. Complex 1 can selectively and sensitively dete
