Research Interests

We are interested in the development of novel pi-structures and synthesis of high performance conjugated materials for organic electronics and sensors.

 

Research Highlight

Ref.: Jiang, Q.; Wei, H.; Hou, X.; Chi, C., Circumpentacene with Open-Shell Singlet Diradical Character. Angew. Chem. Int. Ed. 2023, 62, e202306938. Circumacenes (CAs) are a distinctive type of benzenoid polycyclic aromatic hydrocarbons where an acene unit is completely enclosed by a layer of outer fused benzene rings. Despite their unique structure, the synthesis of CAs is challenging. In this study, we report the successful synthesis of a circumpentacene derivative, representing the largest CA molecule synthesized to date. Analysis shows that it exhibits a moderate open-shell diradical character with a small singlet-triplet excitation energy. Additionally, it has a small HOMO-LUMO energy gap and displays amphoteric redox behavior.
