The organic compound may include an M?-R-T structure, where M?, R and T represent a thiol or silane derivative, a saturated or unsaturated C1 to C20 hydrocarbon group which is substituted or unsubstituted with fluorine (F), and an amino(—NH2) or carboxyl (—COOH) group, respectively.

  • Patent number: 7332369
    Abstract: A method for forming an organic electronic device, which method comprises the steps of: a) forming a negative image of a desired pattern on a substrate or device layer with a lift-off ink; b) coating a first device layer to be patterned on top of the negative image; c) coating one or more further device layers to be patterned on top of the first device layer to be patterned; and d) removing the lift-off ink and unwanted portions of the device layers above it, thereby leaving the desired pattern of device layers. The method allows the formation of a device structure wherein the device layers to be patterned are self-aligned. The method enables a multiplicity of layers to be patterned in a single set of printing and lift-off steps using one pattern which ensures the excellent vertical alignment of edges, which would be difficult to achieve by direct printing. Horizontal alignment can also be achieved. The size of the device features can be reduced below the actual printing resolution.

  • Patent number: 7294560
    Abstract: A method provides a simple yet reliable technique to assemble one-dimensional nanostructures selectively in a desired pattern for device applications. The method comprises forming a plurality of spaced apart conductive elements (12, 20) in a sequential pattern (26) on a substrate (17) and immersing the plurality of spaced apart conductive elements (12, 20) in a solution (23) comprising a plurality of one-dimensional nanostructures (22). A voltage is applied to one of the plurality of spaced apart conductive elements (12, 20) formed in the sequential pattern (26), thereby causing portions of the plurality of one-dimensional nanostructures (22) to migrate between adjacent conductive elements (12, 20) in sequence beginning with the one of the plurality of spaced apart conductive elements (12, 20) to which the voltage is applied.
