9-Ethylcarbazole-3-carboxaldehyde hydrazones

9-Ethylcarbazole-3-carboxaldehyde hydrazones. (Mitsubishi Chemical Industries Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58140069 A2 19 Aug 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. 88107-89-5 is the cas registry number. This chemical is also mentioned in this article. CLASS: IC: C07D209-86; C07D209-88; G03G005-06. APPLICATION: JP 82-20851 12 Feb 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 74 The title compds.

I had excellent org. photosemicond. and are useful as electrophotog. sensitizers when applied as charge-transfer media. Thus, refluxing a mixt. of 22.3 g 9-ethylcarbazole-3-carboxaldehyde [7570-45-8], 13.4 g N-chlorosuccinimide, and 240 mg Bz2O2 in C6H6 for 2 h gave 6-chloro-9-ethylcarbazole-3-carboxaldehyde (II) [88107-92-0] (yield not given). Reaction of 6.4 g with 5.5 g Ph2NNH2.HCl [530-50-7] in MeOH for 4 h at room temp. gave I (R = Cl, R1 = Ph, R2 = H) [88107-98-6] (no yield given). .

Conductive polymer composite system

Conductive polymer composite system.Some chemicals with cas registry numbers like 7570-45-8 and 642-31-9 are also used. Kim, Oh Kil (United States Dept. of the Navy, USA). U. S. Pat. Appl. US 521798 A0 20 Jan 1984, 20 pp. Avail. NTIS Order No. PAT-APPL-6-521 798. (English). (United States of America). CODEN: XAXXAV. APPLICATION: US 83-521798 10 Aug 1983. DOCUMENT TYPE: Patent CA Section: 76 (Electric Phenomena) Section cross-reference(s): 37 A conductive polymer composite system is made by dissolving an electron-donating polymer and a simple (1:1) or complex (1:2) N-methylphenazinium TCNQ salt in a mutual solvent and casting a film of the resulting soln. on a suitable substrate, e.g. Al, under reduced pressure. The anion of the complex salt is simply a complex of neutral TCNQ and the TCNQ radical anion. Preferred polymers have an ionization potential of ~8-12 eV, e.g. poly(vinyl butyral), PMMA, and polycarbonate. Preferred solvents are DMF and DMSO. The max. cond. is achieved when all of the TCNQ salt in the polymer is in the complex form. However, the lowest concn. of TCNQ salt in complex form necessary to achieve a desired resistance is to be used. The films may contain ~50 wt.% overall TCNQ salt. SEM indicates that the films are actually a network of filaments, which are probably polymer-coated microcrystals of TCNQ salt. .
