A microporous metal–organic framework with open metal sites for selective sensing Fe3+, CrO42- and nitrobenzene
A 3D network with the (42·6·83) topology of metal-organic framework possessing an open 1D channel was synthesized by rigid and planar tetracarboxylic acid 5,5’-(1H-2,3,5-triazole-1,4-diyl)diisophthalic acid (H4L). The luminescent properties of 1 shows highly sensitive response to nitrobenzene, Fe3+ and CrO42- through luminescence quenching effects, making it a promising luminescent sensor for nitro aromatic compounds, Fe3+ and CrO42-.
KEY WORDS: Metal-organic framework, Luminescence quenching, Iron(III), Chromate, Nitrobenzene
