Single-molecule magnets (SMMs) are at the forefront of new technological advances in quantum information processing and spintronics. Despite the recent impressive breakthroughs in extending the magnetic blocking temperatures beyond liquid-nitrogen temperatures, significant challenges await in terms of integrating and addressing such compounds in devices. With this ultimate goal in mind, the design of multifunctional SMMs not only allows to imbue molecules of interest with specific properties that would allow for in situ monitoring of the SMM operation in real time, but can also provide critical insights into our understanding of the magnetic behaviour. In this Review, we highlight how magnetism and luminescence can be harmoniously combined within single molecules to achieve these objectives. The key design principles to attain the simultaneous combination of photoluminescence and slow relaxation of the magnetization are discussed, along with an outlook on how such molecules could be beneficial for emerging next-generation spintronics devices.
单分子磁体（SMMs）处于量子信息处理和自旋电子学等新技术进步的前沿。尽管最近在将磁阻塞温度提高到液氮温度以上方面取得了令人瞩目的突破，但在将此类化合物集成到器件中并进行寻址方面仍面临重大挑战。出于这一最终目标，多功能单分子磁体的设计不仅能使感兴趣的分子具备特定性质，从而实现对单分子磁体运行的实时原位监测，还能为我们理解磁行为提供关键见解。在本综述中，我们重点介绍了如何在单分子内将磁性和发光特性和谐结合以实现这些目标。讨论了实现光致发光与磁化缓慢弛豫同时结合的关键设计原则，并展望了此类分子对新兴的下一代自旋电子器件的益处。
