The application of one kind of metal–organic framework (MOF) material used in multiple fields is one of the most interesting research topics. In this work, four new tetra-nuclear cluster-based lanthanide metal–organic frameworks (LnMOFs) [Ln2(BTDB)3(DMA)(phen)]n (Ln = Tb TbMOF, Eu EuMOF, Gd GdMOF, Tb1.830Eu0.170 Tb,EuMOF, 3,5-bis(trifluoromethyl)-4′,4″-dicarboxytriphenylamine = H2BTDB, 1,10-phenanthroline = phen) are obtained based on the ligand of H2BTDB that is synthesized in our laboratory, and the precise single-crystal structure of H2BTDB is obtained for the first time. The white phosphor was obtained by facilely hybridizing two components of the orange-yellow emission phosphor of Tb,EuMOF and the blue luminescence material of triphenylamine according to the trichromatic theory. At the same time, TbMOF, EuMOF, Tb,EuMOF, and the white phosphor can be used for information encryption, demonstrating their potential application in the field of anti-counterfeiting. Tb,EuMOF is also a multi-mode and self-calibrating thermometer within a broad temperature range of 110–300 K. Further studies show that EuMOF is a rapid response sensor for Fe2+, with a very low limit of detection of 2.0 nM, which is much lower than the national standards for Fe2+ (GB 5749-2005, 5.357 μM). It can achieve strong anti-interference detection of Fe2+ in actual samples of tap water and lake water. In addition, EuMOF can also be made into an easy-to-use sensing device of test paper for real-time and visual sensing of Fe2+.

基于四核团簇的镧系金属有机框架作为白色荧光粉、信息加密、自校准温度计和 Fe2+ 传感器
一种金属有机骨架（MOF）材料在多个领域的应用是最有趣的研究课题之一。在这项工作中，四种新的基于四核团簇的镧系金属有机骨架 (LnMOFs) [Ln 2 (BTDB) 3 (DMA)(phen)] n (Ln = Tb TbMOF , Eu EuMOF , Gd GdMOF , Tb 1.830 Eu 0.170 Tb,EuMOF , 3,5-bis(trifluoromethyl)-4',4″-dicarboxytriphenylamine = H 2 BTDB , 1,10-phenanthroline = phen) 基于H 2 BTDB的配体得到本实验室合成的H 2 BTDB ，首次获得了H 2 BTDB的精确单晶结构。该白色荧光粉是根据三原色理论，由橙黄色荧光粉Tb、EuMOF和蓝色发光材料三苯胺两种组分轻松杂化得到的。同时，TbMOF、EuMOF、Tb,EuMOF和白色荧光粉可用于信息加密，展示了它们在防伪领域的潜在应用。Tb,EuMOF也是一种多模式和自校准温度计，温度范围为 110–300 K。进一步的研究表明EuMOF是一种快速响应的Fe 2+传感器，检测限极低，为2.0 nM，远低于Fe 2+国家标准（GB 5749-2005，5.357 μM）。可实现对自来水和湖水实际样品中Fe 2+的强抗干扰检测。此外，EuMOF还可以制成一种简单易用的试纸传感装置，对Fe 2+进行实时、直观的传感。
