摘要：
Y Two new Cd(II) coordination polymers, namely [Cd(L1)(DCTP)](n) (1) and [Cd(L2)(TPA)](n) (2) (L1 = 1,3-bis(5,6-dimethylbenzimidazol-1-yl)propane, L2 = 1,4-bis(5,6-dimethylbenzimidazol-1-yl)-2-butylene, H2DCTP = 2,5-dichloroterephthalic acid, H(2)TPA = terephthalic acid) were solvothermally prepared and characterized. 1 reveals a 2D (4,4)-connected 4,4L10 sheet with the point symbol of {3(2).4.6(2).7}(2) {3(2).6(2).7(2)}. 2 displays a 2D sql network. 1 and 2 can serve as dual luminescent probes to sense acetylacetone (acac) and Fe3+ with low detection limits. The luminescent sensing mechanism of two compounds was investigated in detail. (C) 2021 Elsevier B.V. All rights reserved.
