摘要:A process for the preparation of pure bromoanthraquinones by denitrobrominating corresponding nitroanthraquinones is described. The process comprises treating nitroanthraquinones of the formula I ##STR1## wherein X is hydroxy, mercapto, carboxy or halogen and m is 1, 2, 3 or 4 and n is 1 or 2, in the temperature range from 200° to 350° C. n Bromoanthraquinones of more than 95% purity are valuable starting materials for dye synthesis and can be used directly without further purification.

摘要:Novel tetracyanoanthraquinodimethane polymers and use thereof. The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus. Tetracyanoanthraquinodimethane polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.
