摘要

受到生物系統中組裝體的啟發，化學家們積極開發創新的方法來操控分子間的作用力，並應用於功能性超分子的組裝。其中，使用具有方向性的金屬配位鍵來引導組裝基元，形成特定幾何結構的組裝體，是一種高效的方法。然而至今，沒有系統性的策略能夠預測組裝的行為與結果，因此歸納出一個有效合理的組裝方法仍然是一大挑戰。在此，我們回顧近期的研究進展，探討聯三吡啶配體的分子設計、自組裝機制、超分子質譜鑑定方法及相關動態配位鍵的應用。

Inspired by aesthetic biological assemblies, chemists have explored innovative approaches to manipulating intermolecular interactions in order to create sophisticated supramolecules with functions. Metal coordination-driven self-assembly indeed leads to facile preparation of welldefined nanostructures. However, due to the lack of general principles that could be applied to structure prediction, it remains challenging to construct elaborate metallo-supramolecular architectures in a rational way. To this end, delicate molecular design for building blocks, careful examination of assembly mechanisms, and expeditious methods for structural characterization should be addressed. Here, we discuss our recent advances in the aspects of ligand design, selfassembly methodology, and mass spectrometry analysis of terpyridine-based metallo-supramolecular complexes and highlight the merits of their dynamic features as well.
