Abstract

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 CrO₄^2- through luminescence quenching effects, making it a promising luminescent sensor for nitro aromatic compounds, Fe³⁺ and CrO₄^2-.

KEY WORDS: Metal-organic framework, Luminescence quenching, Iron(III), Chromate, Nitrobenzene
