title: Covalent attachment of porphyrins and ferrocenes to electrode surfaces through direct anodic oxidation of terminal ethynyl groups.
abstract: One with the surface: A method is presented for electrode modification with terminal alkynes and alkenes. Direct oxidation of these moieties leads to efficient grafting onto glassy carbon, gold, platinum, and indium tin oxide surfaces. Various ferrocenes and 5,10,15,20-(4-ethynylphenyl)porphyrin were attached in this way.
