Functionalized langmuir–blodgett films—toward the construction of molecular devices

Control of the orientation of component molecules in Langmuir–Blodgett (LB) films is important for their use in molecular electronics. Cyclodextrins can be given a particular orientation at the air‐water interface by introducing long alkyl chains through the amino, sulfinyl, and sulfide groups (see Figure). This article reviews progress in molecular‐component and supramolecular LB films and photochemical switching systems constructed from them. magnified image
