Formation of a copper(I) iodide cluster based luminescent metal–organic frameworks (LMOFs) and its utilization for the detection of cysteine (Cys) in aqueous solution are reported. The reaction of bis(amidoquinoline) ligand (L) with copper(I) iodide afforded an LMOF {[(Cu2I2)L2]·2DMSO}n (1) with a 44-sql topology linked by Cu2I2 clusters as a thermodynamic product. Time- and temperature-dependent PXRD experiments confirmed that the entire formation process for 1 is kinetically and thermodynamically controlled. Interestingly, LMOF 1 was also obtained under the mechanochemical condition. Moreover, LMOF 1 dispersed in water shows a selective quenching for Cys over other amino acids due to the strong affinity of Cys to copper(I) iodide. On the basis of the NMR data of L isolated from the decomposition of 1, the decomposition–displacement mechanism was proposed for the sensing of Cys. This result might be utilized for the practical detection of Cys because the sensing material can be prepared simply, and the sensing process is performed in aqueous media.

报告了基于碘化铜(I)团簇的发光金属-有机骨架(LMOF)的形成及其在水溶液中半胱氨酸(Cys)检测中的利用。双(amidoquinoline)配体(反应大号)与铜(I)碘化物,得到一个LMOF {[(CU 2我2)大号2 ]·2DMSO} Ñ(1)配有一个4 4 - SQL用Cu连接拓扑2我2个簇作为热力学乘积。时间和温度依赖的PXRD实验证实,在整个形成过程1在动力学和热力学控制。有趣的是,LMOF在机械化学条件下也获得1。此外,由于Cys对碘化铜(I)的强亲和力,分散在水中的LMOF 1对Cys的选择性淬灭作用超过其他氨基酸。根据从1的分解中分离得到的L的NMR数据,提出了分解位移机制以检测Cys。该结果可用于Cys的实际检测,因为感测材料可以简单地制备,并且感测过程在水性介质中进行。
