Description
Summary:Two new Cd2+ coordination polymers (CPs), namely {[Cd(L)(1,4-PDA)]·0.7(C2H5OH)}n (1) and {[Cd(L)0.5(1,8-NDC)·H2O]}n (2) [L = 1,4-bis(5,6-dimethybenzimidazol-1-yl)-2-butene, 1,4-H2PDA = 1.4-phenylenediacetic acid, 1,8-H2NDC = 1,8-naphthalenedicarboxylic acid], were hydrothermally synthesized and characterized. 1 is a (4,4)-layered structure and further extended into a 3D supramolecular network via π–π stacking interactions. 2 features a 2D (3,4)-connected 3,4L83 framework. 1 and 2 can act as luminescence sensors for detecting acetylacetone (acac) and Fe3+ with high sensitivity, selectivity and recyclability. This is the first dual fluorosensors employing CPs for the detection of Fe3+ and acac. The mechanism for the luminescent sensing of acac and Fe3+ was suggested.
