Ref. : Wang, Q.; Gopalakrishna, T. Y.; Phan, H.; Herng, T. S.; Dong, S.; Ding, J.; Chi, C.* Cyclopenta Ring Fused Bisanthene and Its Charged Species with Open-Shell Singlet Diradical Character and Global Aromaticity/Anti-Aromaticity. Angew. Chem. Int. Ed. 2017, 55, 11415-11419.

Cyclopenta ring fused bisanthene and its charged species were synthesized. The neutral compound has open-shell singlet ground state and displays global anti-aromaticity. The dication also exhibits singlet diradical character but has a unique [10]annulenewithin-[18]annulene global aromatic structure. The dianion is closed shell singlet in ground state and shows global aromaticity with 22 π electrons delocalized along the periphery. Our research gave new insight into the design and properties of global aromatic/anti-aromatic systems based on π-conjugated polycyclic hydrocarbons.
