报告摘要：

The quest for high-performance magnetic materials is essential to address the growing demand in information storage and many other technological domains. Despite their extensive use, conventional magnets suffer from significant drawbacks, including energy-intensive fabrication processes and limited access to critical elements. These challenges have stimulated considerable efforts toward developing new molecule-based magnetic materials that retain the key characteristics of traditional magnets while benefiting from the advantages of molecular chemistry. In particular, mild synthetic conditions, structural tunability, and chemical programmability. [1] 

Within this context, the appropriate selection of building blocks is crucial. Redox-active ligands are especially attractive because they could be reversibly oxidized or reduced to stable radical forms, thereby enabling efficient electronic communication between spin carriers and promoting strong magnetic interactions. For example, the M₃ group at the Paul Pascal Research Center reported that post-modification of the two-dimensional coordination polymer Cr(pyrazine)₂Cl₂ with reducing agents yields a new material with a critical temperature of 510 K, well above room temperature. [2] 

Based on previous investigations, this talk will present a series of high-dimensional molecule-based magnetic architectures exhibiting remarkable physical properties arising from strong metal-radical interactions.

报告人简介：

Mengting SUO began her research training at Xi’an Jiaotong University and obtained her master’s degree in 2021, specializing in organic synthetic methodology and radical chemistry. She subsequently pursued and obtained her doctoral degree at the University of Bordeaux and the Paul Pascal Research Center in France (2021–2025), under the supervision of Rodolphe Clérac and Pierre Dechambenoit, focusing on materials that exhibit long-range magnetic ordering above room temperature. Her research currently centers on high-Tc molecule-based magnets and semi-/conducting coordination networks, aiming to develop functional magnetic materials with potential applications.
