Electrically conducting polytriphenylamines

Electrically conducting polytriphenylamines. Ohsawa, Y.Several substances are used for example 107001-70-7 and 15546-43-7 which are their cas registry numbers.; Ishikawa, M.; Miyamoto, T.; Murofushi, Y.; Kawai, M. (Cent. Eng. Lab., Nissan Mot. Co. Ltd., Yokosuka 237, Japan). Synth. Met., 18(1-3), 371-4 (English) 1987. CODEN: SYMEDZ. ISSN: 0379-6779. DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) Section cross-reference(s): 52 To examine the fundamental properties of conducting org. polymer, poly(4,4'-triphenylamine) (PTPA-H), cyclic voltammetric, spectroscopic, and ESR measurements for PTPA-H and a series of triphenylamine oligomers were carried out. Benzidine units of PTPA-H are oxidized almost independently, and the elec. transport mechanism of p-doped PTPA-H is hole hopping among its benzidine units. .

Guiding concept for developing better charge transporting organic materials

Guiding concept for developing better charge transporting organic materials. Takahashi, Ryuichi; Kusabayashi, Shigekazu; Yokoyama, Masaaki (Fac. Eng., Osaka Univ., Suita 565, Japan). Denshi Shashin Gakkaishi, 25(3), 236-42 (Japanese) 1986. CODEN: DSHGDD. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 76 Based on the drift mobility measurements in polymer dispersions of a series of triphenylamine derivs., a guiding concept is proposed for developing the better charge transporting electrophotog. org. materials.In this article, certain chemicals are used. Some of their cas registry numbers are 366-29-0 and 15546-43-7 Intramol. polyfunctionality as a structural min. unit of the hole (e.g., more N-Ph groups in the triphenylamine deriv.), intramol. mobilizability of the hole state among the units as a result of intramol. resonance, and no formation of deep structural carrier traps such as the dimer sites, are essential factors to consider in the mol. design. A compd., N,N,',N'-tetra-(3-methylphenyl)-4,4'-diaminostilbene which fulfills these requirements exhibited excellent drift mobility. .
