Abstract
1-Alkylamino-, 1-dialkylamino-, 1-(4-alkylaryl)-amino-, 1-aralkylamino-, 1-alkyl(aryl) piperazinyl- and 1-aryloxy-4-aroylaminoanthraquinones with negative dichroism (S = - 0.13 + - 0.35, λmax = 445 + 612 nm) in liquid crystal solvents have been obtained and the influence of the substituents on the dichroism and the position of the long wave absorption band of the dyes is considered.Keywords
