英文摘要： This project will focus on the design and synthesis of functional unit with special structures and photo/magnetic properties of d-f heteronuclear complexes based on transition metal ions (3d,4d),lanthanide ions (4f) and organic ligands. The aim is to synthesize new d-f heteronuclear molecular materials via the controllable assembly and structural optimization of the functional units. The contents of the project include: (1) to explore new synthetic methods and study the influence of the raw materials and synthetic conditions; (2) to discover the property-structural correlation of the d-f heteronuclear molecular materials, such as the luminescent properties, the nature of the magnetic interactions between different spin carriers, and the influence to the photo/magnetic properties via the perturbation of photo, thermal and pressure to the variation of the electron configuration, to search new photo and magnetic molecular composites. The emphasis of the project is to carry out the controllable synthesis and tuning the photo/magnetic properties of the d-f heteronuclear molecular materials, to provide valuable suggestions to the molecular design and controllable synthesis in multi-functional molecular materials, and finally to promote the corresponding subjects (such as chemistry and materials) and new technologies (such as molecular electronics and quantum computing devices).
