Hole transporting compound and organic electroluminescence display using the same: Hole transporting compound and organic electroluminescence display using the same. Baek, Gyeong Rim; Kim, Hwan Gyu; Kim, Seong Han; Oh, Dong Ju; Yoo, Han Seong (Samsung SDI Co., Ltd., S. Korea). Repub. Korean Kongkae Taeho Kongbo KR 2002027935 A 15 Apr 2002, No pp. given (Korean). (Korea, Republic Of). CODEN: KRXXA7. CLASS: ICM: C09K011-06. APPLICATION: KR 2000-58743 6 Oct 2000. 251-41-2 is the cas registry number of certain chemical which is used as reagents here. DOCUMENT TYPE: Patent CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Provided are hole transporting compd. having improved thermal property and hole transporting ability, and org. electroluminescence display using the compd. The hole transporting compd. is based on thieno[3,2-b]thiophene. The org. electroluminescence display shows improved thermal property and luminescence efficiency. .

The electronic spectra of thieno[3,2-b]thiophene: The electronic spectra of thieno[3,2-b]thiophene.Some chemicals with cas registry numbers like 251-41-2 are also used. Bertinelli, F.; Brillante, A.; Palmieri, P.; Taliani, C. (Ist. Chim. Fis. Spettrosc., Bologna, Italy). J. Chem. Phys., 66(1), 51-8 (English) 1977. CODEN: JCPSA6. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) The UV spectrum of thiophthene is investigated in the vapor and crystal phase. Two intense absorption systems in the region 3600-40000 cm-1 are assigned to 2 allowed electronic transitions to Bu excited states, while a very weak absorption obsd. in a crystal sepctrum at 34394 cm-1 is assigned to a single-triplet transition allowed by spin-orbit interactions. Ab initio CI computations of the energies of the excited states and relevant singlet-triplet spin-orbit matrix elements provide support for the assignment. The vibrational anal. of the 1st intense absorption system suggests that the mol. has a distorted geometry in the 1st excited electronic state. An explanation is offered of the very different vibrational structure of the vapor and crystal spectra. .
