Crystalline organic metal chalcogenides (OMCs) are a class of organic-inorganic hybrid semiconducting materials with continuous M-X (X = S, Se, Te) networks formed by the combination of metal nodes and chalcogen atoms from the organic ligands, which display great potentials in the fields of optoelectronics, catalysis, sensing, as well as energy conversion and storage. Here, we synthesized a wave-like 2D OMC material, [(AgBF)MeBHS] (Ag-BHSMe), from AgBF and 1,2,3,4,5,6-hexa(methylselanyl)benzene (MeBHS) through a simple homogeneous reaction. In the solid state, Ag-BHSMe exhibits both fluorescence emission at room temperature and phosphorescent emission at 77 K. TEM, SEM, and confocal microscopy revealed that it is an intrinsic blue luminescent microcrystalline material. In addition, we found that it exhibited a highly selective fluorescence enhancement response to Pb in an aqueous solution in the range of 10 to 10 mol L, which demonstrates its potential as a turn-on probe for the detection of lead ions.
晶态有机金属硫属化物（OMCs）是一类有机-无机杂化半导体材料，由金属节点与来自有机配体的硫属原子组合形成连续的 M-X（X=S、Se、Te）网络，在光电、催化、传感以及能量转换和存储等领域具有巨大的应用潜力。在这里，我们通过简单的均相反应，由 AgBF 和 1,2,3,4,5,6-六（甲基硒基）苯（MeBHS）合成了一种波浪状的 2D OMC 材料 [(AgBF)MeBHS]（Ag-BHSMe）。在固态下，Ag-BHSMe 在室温下表现出荧光发射，在 77 K 下表现出磷光发射。TEM、SEM 和共聚焦显微镜显示，它是一种本征的蓝色发光微晶材料。此外，我们发现它在 10 到 10 mol L 的水溶液中对 Pb 表现出高度选择性的荧光增强响应，这表明它有可能作为一种用于检测铅离子的开环探针。
