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

A Ni(II) complex, [Ni2(FDC)2(4,4′-BMIBP)2(H2O)2·3H2O]n (1) (4,4′-BMIBP = 4,4'-bis(2-methyl-imidazolyl)biphenyl, H2FDC = 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. [ABSTRACT FROM AUTHOR]
