Ferrocenylmethylene-bridged calixazulene derivative 3 and bis(1-azulenyl)ferrocenylmet:hane derivative 4 were obtained by the reaction of 6-tert-butylazulene (6) with ferrocenecarbaldehyde (7) in acetic acid. The new bis(l-azulenyl)ferrocenylmethylium ion 5+ was also generated, by the hydride abstraction reaction of the corresponding hydro derivative 4 with DDQ. The novel ferrocene-substituted calix[4J-azulene derivative 3 exhibit a reversible one-step multi-electron oxidation upon cyclic voltammetry.
