4CzIPN, namely 1,2,3,5-Tetrakis(carbazol-9-yl)-4,6-dicyanobenzene, has a fully substituted benzene ring with two cyano groups as electron accepting units at meta-positions to each other and four carbazolyl groups as electron donating units. It is a powerful metal-free organophotocatalyst and also a typical donor–acceptor fluorophore.
