Determination of the Structure and Orientation of Organic Molecules Tethered to Flat Graphitic Carbon by ATR-FT-IR and Raman Spectroscopy

The results unequivocally indicate that molecules electroreduced from their diazonium precursors are not chemisorbed flat on the pyrolyzed photoresist films surface, but rather at an angle, similar to the behavior of Au/thiol self-assembled monolayers, Langmuir−Blodgett films, and porphyrin molecules chemisorbed thermally on silicon and PPF from alkyne and alkene precursors

Scholarcy highlights

  • Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 across all institutions and individuals
  • The structure and orientation of the molecular layers were probed with ATR-FT-IR and Raman spectroscopy
  • A hemispherical germanium ATR element used with p-polarized light at 65° incidence angle yielded high signal/noise IR spectra for monolayer coverage of molecules on pyrolyzed photoresist films
  • The IR spectra are dominated by in-plane vibrational modes in the 1000−2000-cm-1 spectral range and exhibit weaker out-of-plane deformations in the 650−1000-cm-1 region
  • The results unequivocally indicate that molecules electroreduced from their diazonium precursors are not chemisorbed flat on the PPF surface, but rather at an angle, similar to the behavior of Au/thiol self-assembled monolayers, Langmuir−Blodgett films, and porphyrin molecules chemisorbed thermally on silicon and PPF from alkyne and alkene precursors
