摘要：

Here we report the facile derivatization of a cyano-substituted stilbene into higher pi-extended analogues. The cyano-substituted stilbene, which serves as a synthetic scaffold, has a bromo group and a formyl group on its 4- and 4'-position of the phenylene rings and thus readily undergoes selective transformation into other functional groups using various simple organic reactions. The resultant pi-conjugated molecules that contain a cyano-substituted stilbene skeleton exhibit fluorescence in solution and in the solid state. (C) 2019 Elsevier Ltd. All rights reserved.
