Popis:	Ene–diyne systems possessing 1- and 2-azulenyl groups at the periphery were prepared by palladium-catalyzed cross-coupling reaction of 1- and 2-ethynylazulenes with 9-dibromomethylene-9H-fluorene and 9,10-bis(dibromomethylene)-9,10-dihydroanthracene or 2-iodoazulene with 9,10-bis(diethynylmethylene)-9,10-dihydroanthracene under Sonogashira–Hagihara conditions. The redox behavior of the ene–diyne compounds was examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Moreover, a significant color change of the ene–diyne derivatives was observed with visible spectroscopy under electrochemical reduction conditions.
