稀土离子由于其优良的光学、电学和磁学性质，使之在分子材料设计研究中具有重要位置。目前，选择具有大自旋基态或自身具有光学性质的稀土金属离子（单独或辅以过渡金属离子、有机自由基），通过选择适当有机配体，设计、合成具有光、磁性质的稀土基配合物，依然是分子材料设计最具挑战性的课题之一。本项目以稀土基配合物为研究体系，设计多维分子基磁体、单分子磁体（单离子磁体）、单链磁体，同时引入具有荧光性质基团，及配体的合理选择，研究功能性间可能出现的协同效应，以期获得具有光、磁双功能的分子材料。项目研究将结合以往研究成果，从配体选择和设计入手，合成系列稀土基分子材料，并对其光磁性质进行表征。研究中，将考虑到稀土荧光配合物的寿命短，寻找合适的配体通过天线效应制备稳定长寿命的目标化合物, 提高近红外发光的量子效率，并通过分子磁性测量，筛选出数个分子基磁体，进一步寻求分子磁体设计的规律，进而推动分子光、磁材料的研究。

Lanthanides play a special role in molecular materials, thank to their luminescent, electical and magnetic properties. It is one of the biggest challenge to design molecular materials how to choose the Lanthanids with the high-spin ground state and luminescence, and ligands. Lanthanide-based system will be studied in the project to design the multi-dimensional molecular-based magnets, single-molecular magnets (single-ionic magnets), single-chain magnets. Luminescent group will be introduced into the system and ligands will be selected reasonably. We are looking forward to find new bifunctional molecular materials to study the synergistic effect. The project will start off by ligands so as to get lanthanide-based magneto-opticalmaterial. We will focus on the life-time of luminescentce and magnetic property of complexes to get progress in study on molecules with luminescence and magnetism.
