Abstract:
The present invention is drawn to a layered organic device, and a method of forming the same. The method includes steps of applying a first solvent-containing organic layer to a substrate and removing solvent from the first solvent-containing organic layer to form a first solidified organic layer. Additional steps include applying a second solvent-containing organic layer to the first solidified organic layer and removing solvent from the second solvent-containing organic layer to form a second solidified organic layer. The first solidified organic layer can be crosslinked, which suppresses negative impact to components in the first solidified organic layer when the solvent of the second solvent-containing organic layer is deposited on the first solidified organic layer.
Abstract:
The present invention is drawn to an aqueous emulsion composition. The composition includes an aqueous phase and a hydrophobic phase dispersed in the aqueous phase, which includes a plurality of hydrophobic monomers. The monomers are acid-functionalized and hydrophobic, with less than 10% solubility in water. In one aspect, the monomers can be aromatic. Such monomers can be polymerized with other monomers to form latex particulates. A latex can include latex particulates dispersed in an aqueous fluid medium. In one embodiment, latex particulates can include from about 0.1 wt % to about 25 wt % of polymerized hydrophobic acid-functionalized monomer, and at least one other polymerized film-forming monomer. The latex can be formulated as an ink-jet ink.
Abstract:
A molecular system that is reversibly switchable between four states includes two or more ends. At least three rotors and at least two stators are located between the ends. Each of the rotors is capable of rotating when under the influence of an electric field having a predetermined strength. The predetermined strength of the electric field for rotating one of the rotors is different than that of the predetermined strength of the electric field for rotating each of the other rotors. One or more conjugated connecting units links at least one of the at least three rotors and at least one of the at least two stators. The rotation of at least one of the at least three rotors switches the molecular system to one of the four states.
Abstract:
Optical properties of a screen on which an image is being projected are considered. A patterned surface is given a predetermined pattern of color pixels whereby a degree of wavelength selectivity is employed to improve the color qualities of the projected image. A system is provided wherein there is a matching of emission characteristics of a projector to the screen's reflective characteristics.
Abstract:
Asymmetrical 2,5-disubstituted-1,4-diaminobenzenes are provided, along with a process for forming both symmetrical and asymmetrical 2,5-disubstituted-1,4-diaminobenzenes.
Abstract:
Pigment based inks are provided. The inks include a non-polar carrier fluid; and a surface-functionalized pigment particle including a nitrogen-inked moiety to the surface of the pigment particle through a nitrogen link at one end of the nitrogen-linked moiety and a block copolymer having at least two blocks attached at another end, the pigment particle suspended in the non-polar carrier fluid. A combination of an electronic display and an electronic ink employing the pigment and a process for making the pigment-based inks are also provided.
Abstract:
Copolymers and methods using the copolymers control the stability, the homogeneity of mixtures and the chargeability of a nanoparticle. A block copolymer-nanoparticle composition includes first, second and third block units that each include repeating units of respective monomers. The monomer of the first block unit includes a binding group that binds to the nanoparticle. The monomer of the second block unit includes a hydrophobic moiety that provides steric stabilization of the nanoparticle and homogeneity of mixtures of the copolymer-nanoparticle composition in a non-polar medium. The monomer of the third block unit includes a chargeable group that imparts a charge to the nanoparticle. An order of the respective block units in the copolymer and the number of repeating units of the monomer in the respective block units control the stability, the homogeneity of mixtures and the charge of the nanoparticle.
