Metal-free catalyzed intermol. tandem Michael addition/cyclization was developed for the synthesis of benzo[4,5]imidazo[1,2-a]pyridines I [R = H, Me, Ph, etc.; R1 = H, 7-Me, 7,8-Cl2, etc.] from ¦Á-bromocinnamaldehyde and 2-substituted benzimidazoles. The reaction promoted by a simple inorganic base displayed moderate to good yields and good functional group tolerance. The optical properties of some typical products I were investigated. Due to the presence of the benzene ring at the C1-position of compounds I which restricted intramol. motion, as a new type of aggregation-induced emission (AIE) luminogen (AIEgen), they showed very good solid-state fluorescence with quantum yields up to 88.80%. Importantly, the AIE performance of compound I [R = Me; R1 = H] could be useful to detect the nitroarom. explosive picric acid (PA) with a detection limit and quenching constant of 42.5 nM and 7.27 x 104 M-M, resp.
