摘要:
An organic field-effect transistor and a method of making the same include a self-assembled monolayer (SAM) of bifunctional molecules disposed between a pair of electrodes as a channel material. The pair of electrodes and the SAM of bifunctional molecules are formed above an insulating layer, in which each of the bifunctional molecules comprises a functionality at a first end that covalently bonds to the insulating layer, and an end-cap functionality at a second end that includes a conjugated bond. The SAM of bifunctional molecules may be polymerized SAM to form a conjugated polymer strand extending between the pair of electrodes.

摘要:
The present invention describes thin film transistors in which the active channel layer is a thin film of a polycyclic aromatic compound, such as, pentacene, prepared by solution processing a soluble precursor of the polycyclic aromatic compound on a substrate followed by heating to a moderate temperature to convert the precursor back to the polycyclic aromatic compound. The soluble precursors of the polycyclic aromatic compounds are organic solvent-soluble Diels-Alder adducts of polycyclic aromatic compounds, such as, oligothiophene, perylene, benzo[ghi]perylene, coronene and a polyacene with a variety of dienophiles that contain at least one heteroatom. The Diels-Alder adducts can be converted back to pentacene by retro-Diels-Alder reaction at moderate (60-250° C.) temperatures both in bulk, in solution or as thin-films.

The present invention provides a substrate having thereon a patterned small molecule organic semiconductor layer. The present invention also provides a method and a system for producing a substrate having thereon a patterned small molecule organic semiconductor layer. The substrate having thereon a patterned small molecule organic semiconductor layer is produced by exposing a donor substrate having thereon a small molecule organic semiconductor layer to energy to cause the thermal transfer of a small organic molecule onto an acceptor substrate.
摘要:
A molecular manipulator includes a light-sensitive molecule, including a double bond, which changes a cis-trans configuration of the double bond in response to illumination by light of a selected wavelength, and a probe, for example, a probe of a scanned-proximity probe microscope, to which the light-sensitive molecule is attached. A method of making the molecular manipulator includes covalently bonding the light-sensitive molecule to the probe. A method of moving a nanostructure includes controllably grasping, moving, and releasing the nanostructure with the molecular manipulator.
摘要:
In accordance with the first object of this invention soluble derivatives of sexithiophene in which terminal carbons are substituted with various polar groups such as phosphonic esters, phosphonic acids, phosphonates, carboxylic acids, carboxylates, amines, amides, carbamates, and alcohols, each separated from the terminal thiophene rings by one or more methylene groups, are synthesized. An TFT device in accordance with the second objective of this invention employs films of the above sexithiophene derivatives as the semiconducting component. These organic semiconductors are dissolved in common organic solvents and applied to the surface of a substrate using inexpensive, low-temperature solution-based processing such as spin-coating, dip-coating, drop-casting, or microcontact printing.
摘要:
An occupant of a cubicle or office can activate transparent partitions to partially or completely enclose a cubicle and/or office to minimize noise, optimize privacy, lighting, air flow and temperature. This transparent partition is coated with a thin layer material connected to electrodes. Once the occupant decides that changing working conditions (e.g., minimize noise, optimize privacy, adjust lighting, air flow and/or temperature) is needed, the occupant can activate the thin transparency control layer by appropriate electronic control. Movable parts of the partitions may also be adjusted. The transparent partitions may be made darker or opaque. Movable partitions may be used to provide optimized privacy, noise level, lighting, air flow and temperature control. Conversely, the partitions may be made transparent and movable sections retracted to permit greater worker-to-worker interaction.
摘要:
Biobased cross-linked compositions, methods of fabrication and structures, in particular biobased printed wiring boards using the compositions and methods of making the structures are described. Biobased materials such as lignin, crop oils, wood resins, tannins, and polysaccharides and combinations thereof are cross-linked, preferably using heat, a cross-linking agent, and an initiator. The materials fabricated have suitable properties for printed wiring boards which are made by impregnating a fiberglass or biobased cloth with an admixture of the biobased material, cross-linking agent and initiator which is processed by conventional methods to produce a printed wiring board.
