The rational design, synthesis, and characterization of a series of novel perfluorinated dendrons 14a, b, 25a, b, 26a, b, and 18 are described. The dendrimers were designed to have a thiol at the focal point for attachment to a gold surface to enable the fabrication of self- assembled monolayers (SAMs). Perfluorinated tails were attached to the periphery to provide solubility in supercritical carbon dioxide, and to increase the hydrophobicity and ...
