    摘要: An electric field activated molecular system, preferably bi-stable, configured within an electric field generated by a pair of electrodes is provided for use, e.g., as electronic ink or other visual displays. The molecular system has an electric field induced band gap change that occurs via a change (reversible or irreversible) of the extent of the electron conjugation via chemical bonding change to change the band gap, wherein in a first state, there is substantial conjugation throughout the molecular system, resulting in a relatively smaller band gap, and wherein in a second state, the substantial conjugation is destroyed, resulting in a relatively larger band gap. The changing of substantial conjugation may be accomplished in one of the following ways: (1) charge separation or recombination accompanied by increasing or decreasing electron localization in the molecule; or (2) change of substantial conjugation via charge separation or recombination and&pgr;-bond breaking or making. A primary advantage of the molecular system is improved contrast. Because the colorant of the present invention is molecular and thus effectively monoplanar, there should be no backside reflection or excessive scattering from the colorant. A second advantage of the present invention is improved resolution. Finally, each molecule of the present invention will latch to stabilize one or the other of its color states.

    摘要: A gated nanoscale switch operates as a resonant tunneling device. A conductive channel is formed of a pair of conductive molecular wires and a conductive nanoparticle. Each molecular wire is bound, at one end, to the conductive nanoparticle and, at the opposed end, to one of a pair of electrodes. The structure is located upon a dielectric layer that overlies a conductive substrate. The device may be arranged to operate as a switch with the conductive substrate acting as a gate electrode. Alternatively, the device may be employed to measure the electrical (current versus voltage) characteristics of the molecular wires.

    摘要: In accordance with the present invention, a molecular device is provided that can act as a finite state machine, such as a logic device or a memory device. The molecular device includes operating molecules having two or more rotors. Each rotor has an electric dipole moment and multiple discrete rotor configurational states. A rotor can be any suitable and effective group that has an electric dipole moment and multiple discrete rotor configurational states. An individual rotor configurational state can be substantially or completely independent of the rotor configurational states of other rotors. The rotor configurational states can be binary. The molecular configurational state of a multi-stable molecule of a device can be ascertained by measuring conductance.
