Silver cluster-assembled materials (SCAMs) are well-defined crystalline extended materials hallmarked by their unique geometric structures, atomically precise designability and functional modularity. The precise structural features of SCAMs are intrinsically linked to their unique functionalities, and understanding this correlation helps in optimizing their performance and predicting their behavior. In this study, we report for the first time the synthesis of a (3,6)-connected three-dimensional (3D) SCAM, [Ag12(StBu)6(CF3COO)6(TPMA)6]n (designated as TUS 6), TPMA=tris(pyridine-4-ylmethyl)amine by assembling Ag12 cluster nodes with the help of a tridentate linker TPMA. Besides, we also prepared a two-dimensional (2D) SCAM, [Ag12(StBu)6(CF3COO)6(TPEB)6]n (described as TUS 7), TPEB = 1,3,5-tris(pyridine-4-ylethynyl)benzene by reticulating Ag12 nodes with tridentate linker TPEB. This work highlights the influence of flexibility of organic linkers in dictating the spatially extended structures of SCAMs and the properties arising thereof. Characterized by microscopic and diffraction analyses, the SCAMs revealed distinct morphologies, structural robustness, and phase purity.

设计构建两种新型原子精确三维和二维 Ag12 团簇组装材料


银簇组装材料 （SCAM） 是定义明确的晶体扩展材料，其特点是其独特的几何结构、原子精确的可设计性和功能模块化。SCAM 的精确结构特征与其独特的功能有着内在的联系，了解这种相关性有助于优化其性能并预测其行为。在这项研究中，我们首次报道了 （3,6） 连接的三维 （3D） SCAM，[Ag12（StBu）6（CF3COO）6（TPMA）6]n（指定为 TUS 6），TPMA=tris（吡啶-4-基甲基）胺的合成，通过在三齿连接器 TPMA 的帮助下组装 Ag12 簇节点。此外，我们还制备了二维 （2D） SCAM，[Ag12（StBu）6（CF3COO）6（TPEB）6]n（描述为 TUS 7），TPEB = 1,3,5-三（吡啶-4-基乙炔基）苯，通过用三齿接头 TPEB 网化 Ag12 节点。这项工作强调了有机连接子的灵活性在决定 SCAM 的空间扩展结构及其产生的特性方面的影响。通过微观和衍射分析，SCAMs 揭示了不同的形态、结构稳健性和相纯度。
