Aromatic compounds are important in synthetic chemistry, biomedicines, and materials science. As a special type of aromatic complex, transition-metal-based metallaaromatics contain at least one transition metal in an aromatic framework. The chemistry of metallaaromatics has seen much progress in computational studies and synthetic methods, but their properties and applications are still emerging. In recent years, we have disclosed a series of metal-centered conjugated polycyclic metallacycles in which a carbon chain is chelated to a metal center through at least three metal–carbon bonds. These are termed carbolong complexes and exhibit good stability to water, oxygen, light, and heat on account of their polydentate chelation and aromaticity, making them easy to handle. Carbolong complexes are not only special π-conjugated aromatics but also organometallics; therefore, they have the properties of both species. In this Account, we showcase the recent advances in their applications based on their different properties.

Carbolong Metallaaromatics 的独特性能和新兴应用

芳香族化合物在合成化学、生物医学和材料科学中很重要。过渡金属基金属芳烃作为一类特殊的芳烃络合物，在芳烃骨架中至少含有一种过渡金属。金属芳烃化学在计算研究和合成方法方面取得了很大进展，但它们的性质和应用仍在不断涌现。近年来，我们公开了一系列以金属为中心的共轭多环金属环，其中碳链通过至少三个金属-碳键与金属中心螯合。这些被称为碳龙配合物，由于它们的多齿螯合和芳香性，对水、氧气、光和热表现出良好的稳定性，使它们易于处理。Carbolong配合物不仅是特殊的π-共轭芳烃，而且还是有机金属化合物；因此，它们具有两个物种的特性。在此帐户中，我们根据它们的不同属性展示了它们应用程序的最新进展。
