英文摘要: This programme aims to the great scientific question of the function-directed design of new crystalline materials, and focuses on the structural design and property studies of polymetallic functional crystalline complexes. New concepts, methods and systems are expected via this research, and finally the correlationship between structure and properties may be clarified. This programme plans to synthesize ligand-bridged polymetallic complexes, i.e. integrating coordination ions with different magnetic, light, and catalytic properties into a complex, to study the effect of molecular constructions on properties. The final goal is to realize the controllable synthesis of crystalline molecular materials with improved physical properties. On the basis of our previous work, this research aims to the design and construction of new ligand-bridged functional complexes, and to clarify the mechanism of the intermetallic interaction and assembly of the moieties in the molecule. New synthetic methods are expected to find, and polynuclear, nanoclusters and polymeric ordered crystalline complexes with high Tc can be obtained. The magnetic coupling mechanism can be understood, and the applications to chemical luminescence, information storage and catalysis are investigated.
