The present invention relates to a curable composition and a use thereof and, more particularly, to a curable composition and a use thereof, the curable composition comprising: (a) a compound capable of being denatured to a quinone-based compound by oxygen; (b) an amine-based polymeric compound; and (c) an oxygen clathrate structure.

The buffer layer including the functionalized metal nanoparticle according to example embodiments may improve the injection of electrons or holes and the charge mobility between layers in the electronic device, may form ohmic contacts, and may improve the selectivity between electrodes and the buffer layer at the time of forming the buffer layer on the electrodes, thereby improving the efficiency of the electronic device.

Disclosed is a method for forming banks during the fabrication of electronic devices incorporating an organic semiconductor material that includes preparing an aqueous coating composition having at least a water-soluble polymer, a UV curing agent and a water-soluble fluorine compound. This coating composition is applied to a substrate, exposed using UV radiation and then developed using an aqueous developing composition to form the bank pattern. Because the coating composition can be developed using an aqueous composition rather than an organic solvent or solvent system, the method tends to preserve the integrity of other organic structures present on the substrate. Further, the incorporation of the fluorine compound in the aqueous solution provides a degree of control over the contact angles exhibited on the surface of the bank pattern and thereby can avoid or reduce subsequent surface treatments.

Disclosed is a composition, an organic insulating film including the same, an organic thin film transistor including the organic insulating film, an electronic device including the organic thin film transistor and methods of fabricating the same. In the composition, an organic polymer material having a carboxyl group and an organic silane material having an electron-donating group are included to thus realize a structure which may further stabilize an unreacted crosslinking material. Thereby, a hysteresis phenomenon may be decreased and transparency may be increased, thus making it possible to assure stability upon exposure to air. Accordingly, the lifetime of the organic thin film transistor may be lengthened.

According to a method for forming a UV patternable conductive polymer film, vapor-phase polymerization (VPP) may be employed to synthesize a conductive polymer, and a UV-curable polymer resin may be used as a binder to form a conductive polymer film, the method including coating a mixed solution of a binder and an oxidant on a transparent substrate, synthesizing a conductive polymer by vapor-phase polymerization (VPP) on the coating to form a conductive polymer film and patterning the conductive polymer film with UV light. The conductive polymer film may be patterned in a relatively simple manner while maintaining increased conductivity, improved transparency and improved flexibility. Therefore, the conductive polymer film may be used as a material for transparent electrodes of a variety of display devices, e.g., LCD and PDP devices, and electronic devices, e.g., ELs and TFTs.

Disclosed is an organic electronic device, in which a semiconductor layer and source/drain electrodes may be formed from materials of the same type, suitable for a room-temperature wet process, and thus have surface properties similar to each other, thereby decreasing contact resistance between the semiconductor layer and the source/drain electrodes. The materials for formation of the semiconductor layer and source/drain electrodes may be organic semiconductor type materials obtained by adding carbon-based nanoparticles to organic semiconductor materials in predetermined or given amounts. As such, the conductivity of a semiconductor or conductor may vary depending on the amount of carbon-based nanoparticles.

Organic electronic device

Disclosed are methods of fabricating organic thin film transistors composed of a substrate, a gate electrode, a gate insulating film, metal oxide source/drain electrodes, and an organic semiconductor layer. The methods include applying a sufficient quantity of a self-assembled monolayer compound containing a live ion to the surfaces of the metal oxide electrodes to form a self-assembled monolayer. The presence of the live ion at the interface between the metal oxide electrodes and the organic semiconductor layer modifies the relative work function of these materials. Further, the presence of the self-assembled monolayer on the gate insulating film tends to reduce hysteresis. Accordingly, organic thin film transistors fabricated in accord with the example embodiments tend to exhibit improved charge mobility, improved gate insulating film properties and decreased hysteresis associated with the organic insulator.
