Tetraphenylhexaazaanthracenes: 16π Weakly Antiaromatic Species with Singlet Ground States
Constantinides, Christos P.; Zissimou, Georgia A.; Berezin, Andrey A.; Ioannou, Theodosia A.; Manoli, Maria; Tsokkou, Demetra; Theodorou, E.; Hayes, Sophia C.; Koutentis, Panayiotis Andreas (2015)Tetraphenylhexaazaanthracene, TPHA-1, is a fluorescent zwitterionic biscyanine with a closed-shell singlet ground state. TPHA-1 overcomes its weak 16π antiaromaticity by partitioning its π system into 6π positive and 10π ...
