A dendron (2) comprising a focal point (4) and a plurality of fluorinated end groups (9) is disclosed, including one having a thiol, a silane, a carboxylic acid, a phosphonate or another moiety at the focal point suitable for chemisorption to a substrate (3). A self-assembled monolayer comprising a plurality of dendrons bonded to a substrate and a device comprising the self-assembled monolayer are also disclosed.

Fabrication of self-assembled dendron monolayers

A self-assembled monolayer (SAM) is fabricated using either a semi-fluorinated sulphur containing compound, or a sem-fluorinated silane derivative and compressed carbon dioxide (CO) as the solvent medium. The temperature and/or pressure of the compressed COmay be varied during the fabrication process to improve the molecular packing density of the monolayer. By using compressed COas the solvent medium, monolayers with good molecular packing density can be fabricated relatively quickly without the use of environmentally unfriendly solvents.
