Hetero[8]circulenes have been shown to be potential charge transport materials in the field-effect devices. In particular, the hole mobility of the octathia[8]circulene thin-film can reach as much as 9 × 10−3 cm2 V−1 s−1 with on/off current ra

A soluble, green-blue fluorescent, pi-extended azatrioxa[8]circulene was synthesized by oxidative condensation of a 3,6-dihydroxycarbazole and 1,4-anthraquinone by using benzofuran scaffolding. This is the first circulene to incorporate anthracene wi
