Abstract:
One embodiment of the present invention provides a compound for an organic device, the compound comprising a functional group comprising a pyrimidine ring, and/or a functional group comprising a pyrimidine ring, which is included at a terminal of a carbazole-based compound comprising carbazole, wherein an organic thin film is formed by a hydrogen bond between the functional groups.
Abstract:
PURPOSE: A stamp and a method for forming an ultra fine shape are provided to perform a smooth patterning process by forming a multilayer stamp made of an elastic material. CONSTITUTION: A stamp includes a support unit(30), a stamping unit(31), and a coating layer(27). The support unit is made of a first material with an elastic force. The stamping unit is formed on the support unit and is made of a second material with larger intensity than the first material. The coating layer is coated on the stamping layer.

PURPOSE: A producing method of an aqueous graphene solution and a producing method of an aqueous conductive polymer solution are provided to produce grapheme capable of dispersing inside an aqueous solution, and to add the graphene into a conductive polymer composite. CONSTITUTION: A producing method of an aqueous graphene solution comprises the following steps: forming a graphene oxide by oxidizing graphite by processing with an acid solution; dispersing the graphene oxide using a dispersing agent selected form an ionic polymer, or an aqueous conductivity polymer; and reducing the graphene oxide using a reductant. The acid solution is an oxidized acid solution. The oxidized acid is selected from the group consisting of H_2SO_4, KMnO_4, HCl, and HNO_3. The ionic polymer is nafion.
