Preparation of N-(arylmethyleneimino)carbazoles as charge transport compounds for organic photoconductors: Preparation of N-(arylmethyleneimino)carbazoles as charge transport compounds for organic photoconductors.Some chemicals with cas registry numbers like 1592-95-6 are also used. Gairns, Raymond Stevenson; Watson, Anthony Alanzo (Imperial Chemical Industries PLC, UK). Brit. UK Pat. Appl. GB 2249789 A1 20 May 1992, 19 pp. (United Kingdom). CODEN: BAXXDU. CLASS: ICM: C07D209-82. APPLICATION: GB 91-22797 28 Oct 1991. PRIORITY: GB 90-24872 15 Nov 1990. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 74 Title compds. [I; R = carbazolyl group Q1, anilinonaphthyl group Q2; R1 = (substituted) alkyl, -aryl, -aralkyl; R2 = (substituted) alkyl, -aralkyl; X1-X5 = H, group capable of stabilizing a pos. charge on the adjacent C-atom (sic)] were prepd. Thus, 1-(N-ethyl-N-phenylamino)-4-formylnaphthalene was condensed with N-aminocarbazole (prepn. of each given) to give I (R = Q2, R2 = Et, X1 = X2 = X4 = X5 = H) which gave 5 s dark decay from 1100 to 870 V surface potential in an org. photoconductor formulation. .
