Fully Conjugated Azacorannulene Dimer as Large Diazafullerene Fragment
Shingo Ito describes the synthesis of a useful fully conjugated azacorannulene dimer.
Since their discovery in the 1980s, fullerenes have attracted much attention as a molecular form of carbon allotrope. Owing to their curved structure and rich π-electron density, fullerenes exhibit a wealth of interesting phenomena and properties and thus have been studied and tested for applications in various research fields such as electronics, catalysis, and gas storage. Fullerenes have also been an important target of bottom-up synthesis for synthetic chemists. Although the synthesis of C60 from small polycyclic aromatic precursors was achieved, fullerenes of different shapes and sizes are still difficult to synthesize selectively. The group of Professor Shingo Ito at Nanyang Technological University (Singapore) has been studying this synthetic challenge, leading to the title paper.
