Pyridine-Fused Azacorannulene: Fine-Tuning of the Structure and Properties of Nitrogen-Embedded Buckybowls

Heteroatom-embedded buckybowl molecules provide a fundamental molecular framework that has potential applications in various research fields. However, selective introduction of heteroatoms into buckybowls is challenging, and thus, studies investigating the effect of introduced heteroatoms have been limited. Here, we report the synthesis of pyridine-fused azacorannulene molecules. The influence of nitrogen atoms introduced into the peripheral positions on the structural, electronic, and optical properties is discussed.
