Research Project

Abstract

MOFs are one of porous materials, which are useful platform for construction of optoelectronics materials because photofunctional organic compounds can be introduced as ligands into the structures. Especially, MOF can be easily changed in the characteristics by an exclusive property shown by axial ligands called ligand exchange unlike other materials. So that means that the use of chiral ligands as the axial ligands also allows control of the chiral properties of porous space in MOFs. On the other hand, singlet fission is one of multi-exciton generation dynamics due to generating two excitons from one photon. Since the value of quantum yield reaches up to 200%, efficiency of the general reaction can be significantly increased. In this project, by collaboration of singlet fission and control of symmetry using ligand exchange, we will develop new photofunctinal space in MOF.
