摘　　要：An AIE-active azine derivative(1)was facilely synthesized by aldehyde-amine condensation of 2-hydroxy-1-naphthaldehyde and 3-methyl-2-benzothiazolinone hydrazone.It crystallizes in the monoclinic space group P21/n with a=8.2176(5),b=13.1733(7),c=14.5731(8)Å,β=90.521(5)º,and Z=4.Compound 1 exhibits aggregation-induced emission characteristics.In dilute solution,it is non-emissive,while strong emission was observed in the aqueous medium as a result of the molecular aggregation in poor solvent.The powder and crystals of 1 also exhibit strong fluorescence.In its crystal lattice,the molecules stack in a face-to-face style,but there is noπ-πstacking interaction due to the long distance between adjacent molecules.It is the loose stacking mode that blocks the nonradiative decay channel resulting in its AIE effect.
