[2+2+2] Cyclotrimerisation of bisaryl acetylene bearing ferrocenyl units with planar chirality: synthesis of enantiopure conjugated polyferrocene complexes

A new family of highly symmetric and fully conjugated hexaferrocenyl complexes were prepared by a [2+2+2] cyclotrimerisation reaction of the corresponding alkyne monomers. The preliminary electrochemical behaviour of the new complexes was also evaluated by cyclic voltametry.
