摘要：
Two new coordination polymers, {[Cd(BIDPT)(oba)]center dot 0.5H(2)O}(n) (1) and {[Zn(BIDPT)(4,4'-sdb)]center dot 2.25H(2)O}(n) (2) (BIDPT = 4,4'-bis(imidazol-l-yl)diphenyl thioether, H(2)oba = 4,4'-oxydibenzoic acid, 4,4'-H(2)sdb = 4,4'-sulfonyldibenzoic acid), have been solvothermally synthesized and characterized. Both 1 and 2 show 2-fold interpenetrating 3D frameworks with {6(5).8} cds and (6(6)} dia topology, respectively. These two coordination polymers show strong luminescence and their luminescence could be quenched by a series of nitro explosives. Importantly, they exhibit very highly sensitive and selective detection of picric acid compared to other nitro explosives. (C) 2016 Elsevier B.V. All rights reserved.
