A series of α-cyanostilbene derivatives with aggregation-induced enhanced emission （AIEE） was obtained. All the compounds were characterized by UV−vis spectroscopy, fluorescence and nuclear magnetic resonance. These compounds exhibited blue, green and yellow color emission in solid state but non-fluorescent in dilute solutions. The electronic characteristics were examined by GAMESS Interface software package. The results indicate that the luminescence properties are affected by the substituents.
