Abstract
Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.
