Patent number: 7821001Abstract: An organic electronic device. The device includes a first electrode to inject or extract hole, the first electrode including a conductive layer and an n-type organic compound layer disposed on the conductive layer, a second electrode to inject or extract electron, a p-type organic compound layer disposed between the n-type organic compound layer and the second electrode. The p-type organic compound layer forms an NP junction between the n-type organic compound layer and the p-type organic compound layer. The energy difference between a lowest unoccupied molecular orbital (LUMO) energy of the n-type organic compound layer and a Fermi energy of the conductive layer is about 2 eV or less, and the energy difference between the LUMO energy of the n-type organic compound layer and a highest unoccupied molecular orbital (HOMO) energy of the p-type organic compound layer is about 1 eV or less.Type: GrantFiled: April 28, 2008Date of Patent: October 26, 2010Assignee: LG Chem, Ltd.Inventors: Minsoo Kang, Sae Hwan Son, Hyeon Choi, Jun Gi Jang, Sang Young Jeon, Yeon Hwan Kim, Seokhee Yoon, Young Kyu Han

Publication number: 20100133465Abstract: Disclosed is a composite formed by physical and chemical bonding of (a) a carbon nanotube (CNT); and (b) a metal complex with at least one kind of ligand coordinated to a central metal, the CNT being connected to the metal within the metal complex by a direct bond to the metal. Also, provided is a dispersant for a CNT containing a metal complex comprising (i) a complex ion with at least one kind of ligand (Ln) chemically bonded to a central metal; and (ii) a counter ion. By using a metal complex as a dispersant for a CNT, various characteristics possessed by the metal complex can be provided to the CNT, and the dispersibility of the CNT can be meaningfully increased by introducing a ligand and/or a counter ion having dispersion medium-affinitive properties.Type: ApplicationFiled: May 30, 2008Publication date: June 3, 2010Inventors: Won Jong Kwon, Sunmi Jin, Sungho Yoon, Longhai Piao, Young-Kyu Han, Jaehoon Jung, Jong Chan Kim

Patent number: 6878469Abstract: Novel materials for electron injection/transportation and emitting layers can greatly improve the stability of an organic electroluminescent display. Electroluminescent displays incorporating these materials produce blue light at low voltage levels. These novel organic materials include compounds in which 1 to 2 imidazole functional groups are introduced in the 2 or 2,6-site of 9,10 substituted anthracene. An organic electroluminescent display with an organic compound layer of these materials has high efficiency, thermal stability, operationally stability and maintains driving voltage before and after operation.Type: GrantFiled: January 16, 2003Date of Patent: April 12, 2005Assignee: LG Chem, Ltd.Inventors: Seok-Hee Yoon, Jae-Soon Bae, Youn-Gu Lee, Sung-Gap Im, Jae-Chol Lee, Ji-Eun Kim, Kong-Kyeom Kim, Se-Hwan Son, Young-Kyu Han
