Toward the Development of Molecular Wires: A Terpyridine Spacer Containing Polyferrocenylalkyne Linkages

Abstract

The preparation, characterizations, and electrochemical measurements of the terpyridine-ferrocenylalkyne spacers (tpy−C⋮C−(fc)n−C⋮C−tpy; tpy = terpyridyl; fc = ferrocenyl; n = 2, 3) are described. In the electrochemical measurements, the charge could be delocalized to the cyclopentadienyl and ethynyl moieties caused by the built-up charge density upon oxidation of the ferrocenyl moiety.
