Tetradecylferrocene (4, Fc-(CH2)13CH3) was synthesized via lithiation of ferrocene by treatment with tert-butyllithium, followed by alkylation with 1-bromotetradecane. Complex 4 forms a physisorbed ordered molecular monolayeron the surface of highly oriented pyrolytic graphite (HOPG) that was analyzed by scanning tunneling microscopy(STM). It features a lamellar structure with single rows of ferrocenyl moieties separating connecting areas formedby the long alkyl chains which are arranged parallel to each other. The ordering principle of 4 on the surface can berelated to the arrangement of Fc-(CH2)13CH3 molecules in the three-dimensional crystal lattice.
