Abstract

Single-molecule magnets (SMMs), particularly those based on lanthanide(III) (LnIII) coordination compounds, have emerged as promising candidates for next-generation molecular information storage and quantum computing due to their molecular magnetic bistability and slow magnetic relaxation. Beyond the search for better magnetic performance, the design of multifunctional SMMs has also become a key research focus. These multifunctional features are intended to aid interpretation of magnetic properties while also improving the applicability of SMMs in devices. Among several possibilities, luminescence thermometry offers real-time monitoring of SMMs, providing critical information for device integrity and thermal management. However, synthesizing top-performing SMMs integrating luminescence thermometry remains a remarkable challenge. In this context, this review paper explores the latest advancements in LnIII-based SMMs presenting temperature probing through luminescence, focusing on design strategies to optimize both performances. For that, efforts to achieve synergistic functionality through crystal field engineering, polynuclear architectures, and 3d-4f coordination compounds are discussed. By addressing these aspects, the aim is to unlock further possibilities to explore the transformative potential of LnIII-based SMMs for applications in quantum technologies. (AU)
