Photoexcited and ground-state diradical(oid) character in a triquino[3]radialene The unusual [3]radialene motif at the centre of triquino[3]radialene permits exceptional electronic conjugation between the three quinone arms of the molecule, giving rise to a remarkably low-energy and intense absorption spectrum. Since triquino[3]radialene’s initial synthesis in the 1970s, questions have been posed around the molecule’s potential diradical(oid) character.
