摘要: 采用生动的拟人化叙事，讲述了金属锇原子(“小锇”)从构成有毒化合物四氧化锇到转变为功能性“金属核轮烯”分子的奇幻旅程。故事中，小锇在造成生态破坏后深感愧疚，决心改变，并在一位“分子魔法师”的引导下，成功被改造成“金属核轮烯”。魔法师通过二茂铁、二苯铬、格氏试剂等经典案例，深入浅出地阐释了夹心型、半夹心型等金属轮烯的多样性及其广泛应用。最终，小锇通过创新的“共轭碳链成环”法，被构筑成一个结构独特、性质稳定且具广泛应用前景的新型分子，展现了从基础研究到应用创新的科学思维过程。这则故事不仅是一篇有趣的科普童话，更是一堂融汇了化学史、键合理论和材料科学的启蒙课。

Abstract: This article employs a vivid personified narrative to recount the journey of an osmium atom (“Little Os”) from being part of the toxic osmium tetroxide to transforming into a functional “metal-centred annulene”. In the story, after causing ecological damage, Little Os resolved to change. Under the guidance of a “Molecular Magician”, she was successfully transformed into a “metal-centred annulene”. Using classic examples such as ferrocene, bis(h⁶-benzene) chromium, and Grignard reagents, the Magician explained the diversity of metallo-annulenes-including sandwich, half-sandwich, and other types-and their wide range of applications. Ultimately, through an innovative “conjugated carbon chain cyclization” method, Little Os was constructed into a novel molecule with a unique structure, stable properties, and broad application prospects, demonstrating the scientific thought process from basic research to applied innovation. This story is not only an engaging popular science tale, but also an enlightening lesson integrating the history of chemistry, bonding theory, and materials science.
