摘要： Classes of molecules are disclosed which can, for example, be used in molecular switches. The classes of molecules include at least three segments—an electronic donor (“D”), a switchable bridge (“B”), and an electronic acceptor (“A”)—chemically connected and linearly arranged (e.g., D-B-A). The electronic donor can be an aromatic ring system with at least one electron donating group covalently attached; an aromatic ring system with an electron withdrawing group covalently attached is usually employed as the electronic acceptor; and the switchable bridge can be a pi system that can be switched on or off using an external electric field.

摘要： A molecular system that is reversibly switchable between four states includes two or more ends. At least three rotors and at least two stators are located between the ends. Each of the rotors is capable of rotating when under the influence of an electric field having a predetermined strength. The predetermined strength of the electric field for rotating one of the rotors is different than that of the predetermined strength of the electric field for rotating each of the other rotors. One or more conjugated connecting units links at least one of the at least three rotors and at least one of the at least two stators. The rotation of at least one of the at least three rotors switches the molecular system to one of the four states.

摘要： 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.

摘要： An optical sensor is provided, comprising (a) a silicon nanowire of finite length having an electrical contact pad at each end thereof; and (b) a plurality of self-assembled molecules on a surface of the silicon nanowire, the molecules serving to modulate electrical conductivity of the silicon nanowire by either a reversible change in dipole moment of the molecules or by a reversible molecule-assisted electron/energy transfer from the molecules onto the silicon nanowire. Further, a method of making the optical sensor is provided. The concept of molecular self-assembly is applied in attaching functional molecules onto silicon nanowire surfaces, and the requirement of molecule modification (hydroxy group in molecules) is minimal from the point view of synthetic difficulty and compatibility. Self-assembly will produce well-ordered ultra-thin films with strong chemical bonding on a surface that cannot be easily achieved by other conventional methods.

摘要： A particle display device having a monolayer of a bistable polarizable molecule on either side of a gap filled with a liquid containing suspended particles. The monolayers and the liquid filled gap are disposed between patterned electrodes that are used to apply an electric field across the layers of the gap, thus influencing the orientation or the distribution of the suspended particles. The optical transmission or reflectance of the gap is dependent upon the applied electric field. The polarizable monolayers respond to the applied electric field by assuming one of two stable polarized states. The field provided by the dipoles of the molecules in the monolayer remains after the external field is removed, thereby sustaining the electric field influence on the suspended particles of the display device.
