Abstract
A series of N-substituted 1,4-diamino 2,3-dicarboximido-anthraquinone dyes has been synthesized. The location of the dicarboximido moiety in the 2,3-positions permits the elongation of the molecule in a direction collinear with the major axis of the anthraquinone nucleus by attaching substituents at the imido-N. The resulting dyes have improved order parameters, particularly when a phenyl group is directly bonded to the N.Keywords
