2,2-dicyanovinyl was introduced into the Tröger’s base (TB) skeleton under guidance of theoretical calculation to obtain several novel derivatives with predicted good solid-state luminescence. The results of their fluorescence properties indicated that they exhibited a typical aggregation-induced emission (AIE) behavior which is virtually nonemissive in solution but highly luminescent (500–550 nm, yellow–green light) in the solid state. 5a was then chosen as an example to investigate the AIE and the possibility of its AIE was discussed preliminarily. As an AIE-active material, they are expected to have potential application to be used as solid state fluorescence or AIE materials in future.
