Research Interests

Charge-induced intramolecular charge transfer and its applications.
Molecular design of organic semiconductors.
Supramolecular chemistry and self-assembly.
Molecular structures and reaction mechanisms.

Remote control of hydrogen bonds

Remote control of hydrogen bonds can be achieved with the use of pi-conjugated molecules bearing a binding center, a bridge, and a reaction center. When reactions take place at the reaction center, the binding ability of the binding center varies accordingly.

N-type organic semiconductors

N-type organic semiconductors can be obtained by substituting electron withdrawing groups to p-type frameworks. F-substituted system has larger internal reorganization energy due to the additional contribution of C-F bond. However, CN-substituted system has smaller reorganization energy by extending electron delocalization in a nonbonding fashion.
