A novel 3D Zn(II) coordination polymer for highly luminescent sensing of nitro compounds

A novel 3D coordination polymer [Zn2.5(L)(trz)2(H2O)2]·2H2O (1) (H3L = 5-(4-carboxybenzyloxy)isophthalic acid, trz = triazole) has been synthesized hydrothermally. Compound 1 displays a 3D (3,8)-connected net with (53)2(58·64·78·84·94) topology. The luminescent property of 1 dispersed in different solvents as well as nitrobenzene have been investigated systematically, demonstrating high sensitivity for the detection of nitro compound via a fluorescence quenching mechanism.509
