Non-Planar Polycyclic Aromatic Molecules Including Heterole Units

Abstract

Recent developments in non-planar polycyclic aromatic molecules bearing heterole units have been reviewed, including internally and externally heteroatom doped corannulenes, rim and benzylic heteroatom doped sumanenes, hexapyrrolohexaazacoronenes, and hetero[n]circulenes.

Synthesis and Properties of Azahomocorannulenyl Cations and Radicals

“…Previously we reported azapentabenzocorannulene 1 [27,28] and diazapentabenzocorannulenium [29] as nitrogen-embedded corannulene molecules (Figure 1C). [30,31] In our continuous research, we decided to design and synthesize a ring-expanded analog of molecule 1. Herein, we report on the synthesis and properties of azahomocorannulene derivatives 2, [32][33][34] in which one of the hexagons in the corannulene core of 1 is substituted by a heptagon ring.…”
