Aromatic 3,5-Di(2′,4′-dicarboxylphenyl)benozoic acid based coordination polymers as luminescent sensor for the sensitive detection of chromate anions in aqueous solution

Based on the mixed ligands strategy of 3,5-di(2′,4′-dicarboxylphenyl)benozoic acid and 1,4-bis(imidazol-1-yl) benzene, two (3,4,4)-c coordination polymers were designed, with excellent recyclable, selective, and sensitive detection of Cr(VI) anions in aqueous solution.412
