Abstract
Ferrocenes derivatized with a terminal lithioacetylide group react rapidly with unconnected glassy carbon and gold electrodes, giving up to monolayer-level surface coverage. The molecule-to-surface bonding is sufficiently robust to resist sonication, extended storage under dinitrogen, and thousands of repetitive voltammetric scans through the ferrocenyl oxidation wave. This "spontaneous" modification method provides a non-electrochemical pathway to the strong, apparently covalent, attachment of alkynyl-linked molecular tags to carbon and metal surfaces.
