By varying the fluorescent tags of resorcin[4]arene-based tetracarboxylic acids from phenyl to naphthyl, two highly luminescent metal-organic frameworks (MOFs), namely, [Zn2(TPC4A)(DMF)(H2O)4]·3H2O (1) and [(CH3)2NH2]2[Zn(TNC4A)]·4H2O (2), were successfully achieved (TPC4A = 2,8,14,20-tetra-phenyl-6,12,18,24-tetra-methoxy-4,10,16,22-tetra-carboxy-methoxy-resorcin[4]arene and TNC4A = 2,8,14,20-tetra-1-naphthal-6,12,18,24-tetra- methoxy-4,10,16,22-tetra-carboxy-methoxy-resorcin[4]arene). Compound 1 features a unique 2D network, while 2 exhibits a fascinating 3D framework. The highly selective detection of small organic molecules as well as Fe(2+) and Fe(3+) was performed for 1 and 2 as fluorescent sensors. Remarkably, luminescent 1 and 2 were used as sensory materials for the sensing of various amine vapors with high selectivity and rapid response. Most strikingly, clear fluorescence "on-off" switch-functions toward small organic molecules as well as amine vapors were also explored for luminescent 1 and 2.
通过将基于间苯二酚[4]芳烃的四羧酸的荧光标签从苯基变为萘基，成功制备了两种高发光金属有机框架（MOF），即[Zn2(TPC4A)(DMF)(H2O)4]·3H2O（1）和[(CH3)2NH2]2[Zn(TNC4A)]·4H2O（2）（TPC4A = 2,8,14,20-四苯基-6,12,18,24-四甲氧基-4,10,16,22-四羧基甲氧基间苯二酚[4]芳烃，TNC4A = 2,8,14,20-四-1-萘基-6,12,18,24-四甲氧基-4,10,16,22-四羧基甲氧基间苯二酚[4]芳烃）。化合物1具有独特的二维网络，而化合物2则呈现出迷人的三维框架。作为荧光传感器，对1和2进行了对小有机分子以及Fe(2+)和Fe(3+)的高选择性检测。值得注意的是，发光的1和2被用作传感材料，用于高选择性和快速响应地检测各种胺蒸气。最引人注目的是，还探索了发光的1和2对小有机分子以及胺蒸气的清晰荧光“开-关”开关功能。
