The development of metal complexes for optoelectronic applications is a fertile area of research. In contrast to the rigorous development of mononuclear metal complexes, dinuclear species have been less well studied and their fundamental chemistry and applications are under-explored. However, dinuclear species present special properties and functions compared with mononuclear species as a consequence of tuning the bridging ligands, the cyclometalated ligands or the two metal centers. More recently, dinuclear species have enabled important breakthroughs in the fields of OLEDs, photocatalytic water splitting and CO2 reduction, DSPEC, chemosensors, biosensors, PDT, smart materials and so on. Here we present an overview of recent developments of dinuclear metal complexes, their multifunctional properties and their various applications. The relationship between structure and property of dinuclear species and important factors which influence device performance are discussed. Finally, we illustrate some challenges and opportunities for future research into dinuclear metal complexes. This review aims to provide an up-to-date summary and outlook of functional dinuclear metal complexes and to stimulate more researchers to contribute to this exciting interdisciplinary field.
金属配合物在光电应用方面的发展是一个富有成效的研究领域。与单核金属配合物的严格发展相比，双核物种的研究较少，其基础化学和应用仍未得到充分探索。然而，双核物种由于桥连配体、环金属化配体或两个金属中心的调谐，呈现出与单核物种不同的特殊性质和功能。最近，双核物种在 OLEDs、光催化水分解和 CO2还原、DSPEC、化学传感器、生物传感器、PDT、智能材料等领域取得了重要突破。在这里，我们综述了双核金属配合物的最新发展、它们的多功能性质及其各种应用。讨论了双核物种的结构与性质之间的关系以及影响器件性能的重要因素。最后，我们说明了双核金属配合物未来研究的一些挑战和机遇。本综述旨在提供功能双核金属配合物的最新总结和展望，并激发更多的研究人员为这一令人兴奋的跨学科领域做出贡献。
