Reaction of Cd(NO)·4HO with 5-fluoro-1,3-bis[2-(4-pyridyl)ethenyl]benzene (5-F-1,3-bpeb) and 1,3-benzenedicarboxylic acid (1,3-HBDC) under the solvothermal conditions gave rise to a two-dimensional metal-organic framework (MOF) [{Cd(5-F-1,3-bpeb)(1,3-BDC)}·0.5DMF·2HO] (1). Compound 1 was postmodified by a photodimerization reaction between 5-F-1,3-bpeb ligands to yield [{Cd( syn-dftpmcp)(1,3-BDC)}·0.5DMF·HO] ( syn-dftpmcp = syn-3,4,12,13-tetrakis(4-pyridyl)-8,17-bisfluoro-1,2,9,10-diethano[2.2]metacyclophane) (2). Compounds 1 and 2 have 2D networks built from linking one-dimensional [Cd(1,3-BDC)] chains via 5-F-1,3-bpeb or syn-dftpmcp bridges. After such a post-synthetic modification, compound 2, relative to 1, can probe Al by using a luminescent quenching approach with much higher selectivity and sensitivity.
在溶剂热条件下,Cd(NO)·4HO 与 5-氟-1,3-双[2-(4-吡啶基)乙烯基]苯(5-F-1,3-bpeb)和 1,3-苯二甲酸(1,3-HBDC)反应生成二维金属有机骨架(MOF)[{Cd(5-F-1,3-bpeb)(1,3-BDC)}·0.5DMF·2HO](1)。通过 5-F-1,3-bpeb 配体之间的光二聚反应对化合物 1 进行后修饰,得到[{Cd(syn-dftpmcp)(1,3-BDC)}·0.5DMF·HO](syn-dftpmcp = syn-3,4,12,13-四(4-吡啶基)-8,17-双氟-1,2,9,10-二乙氧基[2.2]环丙烯)(2)。化合物 1 和 2 通过将一维[Cd(1,3-BDC)]链通过 5-F-1,3-bpeb 或 syn-dftpmcp 桥连接来构建 2D 网络。经过这种后合成修饰后,与 1 相比,化合物 2 可以通过使用发光猝灭方法更灵敏、更有选择性地探测 Al。
