, p. 648 - 655 (2021)
Hetero[8]circulenes have emerged as novel functionalized heteronanographenes that show various promising functions such as bright fluorescence, charge transporting, and redox reactivities. One of the effective synthetic strategy is the fold-in type oxidat

The new synthetic method of indolizino[3,4,5-ab]isoindoles (INIs) by an acid-induced intramolecular cyclization of 1,2-di(1H-pyrrol-2-yl)benzenes has been developed. This protocol can be applied to the preparation of INI derivatives with electron-donating and -withdrawing groups as well as azaINIs.

Tetrabenzotetraaza[8]circulene (1) has been synthesized in good yield by a "fold-in" oxidative fusion reaction of a 1,2-phenylene-bridged cyclic tetrapyrrole. X-ray diffraction analysis of 1 has revealed a planar square structure with a central cyclooctat
Calix[2]bispyrrolylarenes: New expanded calix[4]pyrroles for fluorometric sensing of anions via extended π-conjugation
