Abstract

Asymmetric, end-functionalized thiophene oligomers capable of self-assembly and covalent bonding to silicon surfaces have been synthesized. Monolayer films were made using solution or Langmuir-Blodgett deposition techniques. Characterization of the films by AFM and ellipsometry confirms the presence of a single monolayer. The molecular orientation with respect to the surface was evaluated using multi-angle NEXAFS spectroscopy. Initial results using these materials in organic field-effect transistors are also presented.
