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.
摘要翻译：提供了在由一对电极产生的电场内配置的电场活化分子系统，优选双稳态，用于例如电子墨水或其它视觉显示器。分子系统具有电场诱导的带隙变化，其通过经由化学键合改变的电子共轭程度的变化（可逆的或不可逆的）发生，以改变带隙，其中在第一状态下，在整个分子系统，导致相对较小的带隙，并且其中在第二状态下，基本共轭被破坏，导致相对较大的带隙。基本共轭的改变可以通过以下方式之一来实现：（1）伴随着分子中电子定位增加或减少的电荷分离或重组; 或（2）通过电荷分离或重组和断裂或制造改变基本共轭。分子系统的主要优点是对比度提高。因为本发明的着色剂是分子的，因此有效地是单面的，所以不应该有着色剂的背面反射或过度的散射。本发明的第二个优点是分辨率提高。最后，本发明的每个分子将锁定以稳定其一个或多个其颜色状态。

摘要： A method is provided for printing electronic and opto-electronic circuits. The method comprises: (a) providing a substrate; (b) providing a film-forming precursor species; (c) forming a substantially uniform and continuous film of the film-forming precursor species on at least one side of the substrate, the film having a first electrical conductivity; and (d) altering portions of the film with at least one conductivity-altering species to form regions having a second electrical conductivity that is different than the first electrical conductivity, the regions thereby providing circuit elements. The method employs very simple and continuous processes, which make the time to produce a batch of circuits very short and leads to very inexpensive products, such as electronic memories (write once or rewriteable), electronically addressable displays, and generally any circuit for which organic electronics or opto-electronics are acceptable.

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.

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： The present invention provides a printer and media solution that is conducive to briefcase-compatible compactness, battery operation, and media reuse. The printer consists of a low power, electrode array that images the surface of a paper-like, rewritable sheet. The sheet is responsive to pixel-sized electric fields produced by each electrode, resulting in a pixel array that is imaged in response to field polarity. The sheet is coated with a rewritable colorant that is a highly energy efficient, bistable, bi-modal molecular layer, requiring energy only to change an image, not to hold or illuminate it.
