Abstract: A molecular system is 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 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 a molecular conformation change, based on a rotor/stator construction of the molecular system, involving a rotating portion (rotor) connected between to stationary portions (stators). 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.

An electrical fringe field or through field is used to transform targeted pixels by switching light valve molecules between a first non-transparent state and transparent state, providing information content on the adjacent pixel-patterned imaging layer.

Abstract: A route to the fabrication of electronic devices is provided, in which the devices consist of two crossed wires sandwiching an electrically addressable molecular species. The approach is extremely simple and inexpensive to implement, and scales from wire dimensions of several micrometers down to nanometer-scale dimensions. The electronic devices can be used to produce crossbar switch arrays, logic devices, memory devices, and communication and signal routing devices. The construction of molecular electronic devices is achieved on a length scale than can range from micrometers to nanometers via a straightforward and inexpensive chemical assembly procedure. The molecular switchable devices in the cross-bar geometry are configurable while the conformational change is controlled by intramolecular forces that are stronger than hydrogen bonding.

Abstract: 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.
