Patent number: 7951965Abstract: The present invention discloses a phenanthrene derivative having the following structure: wherein Ar1 and Ar2 independently are phenyl, nathphyl, heterocyclic group, polycyclic aromatic or polycyclic heterocyclic group with at least one conjugated substituent. The conjugated substituent can be an electron withdrawing group or electron donating group. The phenanthrene derivatives have semiconductor properties of electron transfer, electroluminescence (EL), and photoluminescence (PL). Intermolecular stacking can be avoided and electron-luminescent emission stability is enhanced when the derivatives are applied as a light-emitting material in organic EL devices due to the presence of the two stereo cyclopentane rings, such as a host compound or a dopant emitting blue light.Type: GrantFiled: February 4, 2005Date of Patent: May 31, 2011Assignee: Industrial Technology Research InstituteInventors: Chi Shen Tuan, Zong-Wei Tsai, Ching-Ian Chao, Shyue-Ming Jang, Chia-Kuo Yen

Publication number: 20100021622Abstract: Apparatus and method for forming multilayer polymer thin film. The method uses a solution container with a gap to prevent the huge amount of solution from directly falling on the first layer. Then the wet film is formed by moving the container with the thin film thickness is decided by the distance between the gap and the substrate. The wet film is dried in a very short time by the heater therefore there is no time for the second solvent to dissolve the first layer. The method can effectively achieve the large-area and multilayer structure in organic devices through solution processing.Type: ApplicationFiled: July 24, 2008Publication date: January 28, 2010Applicant: National Chiao Tung UniversityInventors: Hsin-Fei Meng, Sheng-Fu Horng, Hsin-Rong Tseng, Chi-Shen Tuan

Patent number: 7026275Abstract: A method of reducing the photoelectric device leakage current caused by residual metal ions in conjugated polymer. A chelating agent is added to a conjugated polymer material, thereby the conductivity and mobility of metal ions under an electric field are reduced due to the chelation of metal ions by the chelating agent; therefore, the leakage current is reduced and the stability of devices is improved. Furthermore, the activity of metal ions is reduced after the metal ions are chelated by the chelating agent, improving the stability of the material and the devices. A conjugated polymer composition is also provided.Type: GrantFiled: August 5, 2003Date of Patent: April 11, 2006Assignee: Industrial Technology Research InstituteInventors: Kuo-Yu Chen, Chi-Shen Tuan, Wan-Jung Teng, Shinn-Jen Chang

Patent number: 5415817Abstract: An improved injection/compression molding process for the manufacturing of high quality concave optical lenses of thin thickness. A thermoplastic material is injected into a mold cavity of an injection/compression molding machine, the mold cavity is designed to have adjustable thickness and is initially set at a thickness greater than the lens to be produced. After the amount of the plastic injected fills the enlarged cavity, the thickness of the cavity is gradually reduced by exerting a compressional force on the thermoplastic material inside the mold cavity. During the compression stage, the injection continues and the excess thermoplastic material is squeezed into an overflow pocket inside the injection/compression mold. The injection apparatus can be switched into a pressure holding mode during and after the compression stage to prevent any backflow and post-injection shrinkage.Type: GrantFiled: October 22, 1993Date of Patent: May 16, 1995Assignee: Industrial Technology Research InstituteInventors: Po-Ling Shiao, Chien-Tsung Wu, Chi-Shen Tuan, Tzong-Ming Yeh
