摘要： Bistable molecules are provided with at least one photosensitive functional group. As thus constituted, the bistable molecules are photopatternable, thereby allowing fabrication of micrometer-scale and nanometer-scale circuits in discrete areas without relying on a top conductor as a mask. The bistable molecules may comprise molecules that undergo redox reactions, such as rotaxanes and catenanes, or may comprise molecules that undergo an electric-field-induced band gap change that causes the molecules, or a portion thereof, to rotate, bend, twist, or otherwise change from a substantially fully conjugated state to a less conjugated state. The change in states in the latter case results in a change in electrical conductivity.

摘要： A molecular system is provided for nanometer-scale reversible electronic and optical switches, specifically, electric field-activated molecular switches that have an electric field induced band gap change that occurs via rotation of rotor units connected to immobile stator units. The molecular system has two branches on one side of an immobile junction unit and one or two branches on the opposite side to thereby provide “Y” and “X” configurations, respectively. The ends of the branches opposite the junction unit are connected to, or electrically associated with, other molecular systems or substrates, such as electrodes. The rotor units each rotate between two states as a function of an externally-applied field. Both multi-stable molecular mechanical devices and electric field-activated optical switches are provided.

摘要： A molecular system is provided for nanometer-scale reversible electronic and optical switches, specifically, electric field-activated molecular switches that have an electric field induced band gap change that occurs via a molecular conformation change or a tautomerization. Changing of extended conjugation via chemical bonding change to change the band gap is accomplished by providing the molecular system with one rotating portion (rotor) and two or more stationary portions (stators), between which the rotor is attached. The molecular system of the present invention has three branches (first, second, and third branches) with one end of each branch connected to a junction unit to form a “Y” configuration. The first and second branches are on one side of the junction unit and the third branch is on the opposite side of the junction unit. The first branch contains a first stator unit in its backbone, the junction unit comprises a second stator unit, and the first branch further contains a rotor unit in its backbone between the first stator unit and the second stator unit. The second branch includes an insulating supporting group in its backbone for providing a length of the second branch substantially equal to that of the first branch, wherein the rotor unit rotates between two states as a function of an externally-applied field.

摘要： 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.

摘要： Molecular systems are provided for electric field activated switches, such as a crossed-wire device or a pair of electrodes to which the molecular system is linked by linking moieties. The crossed-wire device comprises a pair of crossed wires that form a junction where one wire crosses another at an angle other than zero degrees and at least one connector species connecting the pair of crossed wires in the junction. The connector species comprises the molecular system, which has an electric field induced band gap change, and thus a change in its electrical conductivity, that occurs via one of the following mechanisms: (1) molecular conformation change; (2) change of extended conjugation via chemical bonding change to change the band gap; or (3) molecular folding or stretching. Nanometer-scale reversible electronic switches are thus provided that can be assembled easily to make cross-bar circuits, which provide memory, logic, and communication functions.
