Outline of Final Research Achievements

Three major projects have been done for this research. 1), by combining redox-active ligand with anthraquinone functional groups and Mn(II) cations, a new metal-organic framework is prepared, namely Mn-AQDC. This MOF exhibited not only a flexible structure, but also a novel electrochemical mechanism is observed when it was used as a cathode material of Li-ion batteries. A high specific capacity, 200mAh/g is also achieved. 2), the attempt of hybridizing carbon nanotubes and nanoparticles of MOFs are performed, while the result is not positive. In most case, amorphous product was obtained. 3) A further study on the Mn-MOF is to tune its physical properties with electron donor organic guest molecules. With a crystal sponge method, the structures of new guest-MOF complexes are achieved and charge transfer phenomena were observed with solid-state reflectance, EPR and magnetism. Referencing with the charge transfer between pure donors and ligands, charge transfer was promoted in MOFs.
