The actinide-polyoxometalate complexes show vast scientific and practical potential in radiochemistry owing to their high thermal stability and radiation-resistant nature. However, the actinide-polyoxometalate coordination polymers (CPs) with 2D or 3D structures have not been reported. In this project, we plan to employ actinide metal ions, polyoxometalate molecules and organic ligands as starting materials to obtain a series of novel actinide-polyoxometalate CPs with optimized synthetic routes via step by step reactions based on molecular design. Various characterizations involving X-ray diffraction, synchrotron radiation and Raman spectroscopic techniques will be conducted to investigate the structure-function relationships. The bonding nature of actinides in these compounds will be explored through theoretical calculations. The actinide-polyoxometalate CPs with stable structure and high performance will be screened out to explore their catalytic properties and catalytic mechanism. It is expected that this project will enrich the library of actinide solid materials，and provide the reference for the synthesis of novel actinide-based functional materials and their applications in catalyst.
