## Abstract Rare redβfluorescent fluorene derivatives have been designed and synthesized. The longβwavelength red fluorescence is achieved by incorporating a di(4βtolyl)amino or diphenylamino electron donor and a dicyanovinyl electron acceptor. The singleβcrystal Xβray structures of the di(4βtolyl)
