资源简介：
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 negative cyanines.
The synthesis of TPHA-1 is low yielding and accompanied
by two analogous TPHA isomers: the deep red, non-charge-separated,
quinoidal TPHA-2, and the deep green TPHA-3 that partitions into two equal but oppositely charged 8π cyanines.
The three TPHA isomers are compared.
