A polycatenated nickel(II) coordination polymer as a luminescence sensor for nitrofurantoin in aqueous medium

A Ni(II) complex, [Ni 2 (FDC) 2 (4,4′-BMIBP) 2 (H 2 O) 2 ·3H 2 O] n ( 1 ) (4,4′-BMIBP = 4,4’-bis(2-methyl-imidazolyl)biphenyl, H 2 FDC = 2,5-furandicarboxylic acid) was hydrothermally synthesized and structurally characterized. Complex 1 possesses a polycatenated architecture based on an undulated (4,4)- sql layer. Complex 1 can be used for the selective detection of nitrofurantoin (NFT) in aqueous solutions. The luminescence quenching mechanism of complex 1 is attributed to the competitive absorption.
