Abstract A series of novel 1-amino and 1, 4-diamino-9, 10-anthraquinones, substituted with different alkyl groups, were synthesized as the result of alkylation with amino substituents. All the obtained aminoanthraquinone derivatives were characterized by NMR, IR spectroscopy and mass spectrometry. The spectroscopic properties of these compounds were determined by using UV–Vis spectroscopy in acetonitrile, and in the mixture of ...
