Carbazole/fluorene-substituted 5-phenyl-2,2′-bipyridine D–π–A fluorophores: photophysical data, hyperpolarizability and CT-indices

A new series of D–π–A push–pull fluorophores containing 2,2′-bipyridine domain acceptor with terminal electron-donating carbazole/fluorene groups has been reported and those exhibit good fluorescence performance.
