| The talk will focus on self-assembled monolayer (SAM) of biphenyl thiolates on gold, which is a two-dimensional array of well-packed molecules at a surface with a film thickness of £ 2 nm. The structure of these SAMs will be discussed, and it will be shown that they form stable, molecularly engineered surfaces. These surfaces were used in two-dimensional nucleation and growth experiments, and it was found that the morphology of amino acid crystals is controlled by the chemistry of the SAM on which it nucleates. Surface-initiated polymerization from these SAMs results in a highly dense polystyrene brush. When SAMs of biphenyl thiolate on gold are irradiated by e-beam, they behave as positive photoresist. |
