ABSTRACT:
A method of attaching a molecular layer to a substrate includes attaching a temporary protecting group(s) to a molecule having a molecular switching moiety with first and second connecting groups attached to opposed ends thereof. The temporary protecting group(s) is attached to the first and/or second connecting group so as to cause the opposed ends of the switching moiety to exhibit a difference in hydrophilicity such that one of the ends remains at at least one of a water/solvent interface and a water/air interface, and the other end remains in air during a Langmuir-Blodgett (LB) process. An LB film is formed on the interface. The temporary protecting group(s) is removed. The substrate is passed through the LB film to form the molecular layer chemically bonded on the substrate. The difference in hydrophilicity between the opposed ends causes formation of a substantially well-oriented, uniform LB film at the interface.
