Discrete spherical metallo-organic capsules at the nanometer scale, especially those constructed from unique building blocks, have received significant attention recently because of their fascinating molecular aesthetics and potential applications due to their compact cavities. Here, the synthesis and characterization of a hexapodal, branched terpyridine ligand are presented along with the nearly quantitative self-assembly of the resulting tetrameric metallo-nanosphere. This metallo-nanosphere exhibited four quasi-triangular and six rhombus-like facets, all of which were made by the same hook-like bis-terpyridine. Collision-induced dissociation experiments were done to investigate overall stability. The metallo-architecture and host-guest chemistry were investigated with coronene and fully characterized by 1D and 2D NMR, ESI-MS, and transmission electron microscopy. Furthermore, this metallo-nanosphere was observed to hierarchically self-assemble into berry-type structures in an acetonitrile/methanol mixture, by virtue of counterion-mediated attractions. The functional molecular metallo-nanosphere presented here expands the reach of terpyridine coordination systems into molecular containers and other model systems.

纳米尺度的离散球形金属有机胶囊，特别是那些由独特的构建块构建的胶囊，最近因其迷人的分子美学和由于其紧凑的腔体而产生的潜在应用而受到了极大的关注。在这里，介绍了六足支链三联吡啶配体的合成和表征，以及所得四聚体金属纳米球的近乎定量的自组装。该金属纳米球表现出四个准三角形和六个菱形小面，所有这些小面都是由相同的钩状双三联吡啶制成。进行碰撞诱导解离实验以研究整体稳定性。用晕苯研究了金属结构和主客体化学，并通过 1D 和 2D NMR、ESI-MS、和透射电子显微镜。此外，通过反离子介导的吸引力，观察到这种金属纳米球在乙腈/甲醇混合物中分层自组装成浆果型结构。这里介绍的功能性分子金属纳米球将三联吡啶配位系统的范围扩展到分子容器和其他模型系统中。
