cadmium-based 3D microporous metal-organic framework [Cd3 (cia)2 (4,4′-bipy) (H2O)2]n (MOF-1, H3cia = 2-(4-carboxylphenoxy)terephthalic acid, 4,4′-bipy = 4,4-bipyridine) was synthesized by choice of a V-shaped asymmetrical tricarboxylate ligand, exhibiting impressive high thermal stability and water stability. More importantly, it acts as luminescence sensor, showing highly selective and sensitive
一种发光活性镉基3D微孔金属有机骨架[Cd 3 (cia) 2 (4,4'-bipy) (H 2 O) 2 ] n (MOF- 1 , H 3 cia = 2-( 4-羧基苯氧基)对苯二甲酸,4,4'-双吡啶 = 4,4-联吡啶)是通过选择 V 形不对称三羧酸酯配体合成的,表现出令人印象深刻的高热稳定性和水稳定性。更重要的是,它作为发光传感器,通过猝灭效应对水溶液中的硝基苯、Fe 3+、Cr 2 O 7 2-表现出高选择性和灵敏的检测。以及 NB、Fe 3+ 的检出限 (LOD) 值和Cr 2 O 7 2−分别为5.35 × 10 -5 M, 7.06 × 10 -5 M, 1.82 × 10 -5 M。此外,MOF- 1还可以通过有效的能量转移对 Tb 3+离子表现出优异的天线探测性能。一般而言,MOF- 1的优异光学传感活性和敏化特性归因于活性金属位点和可接近的多孔结构。
