Synthesis and spectral characterization of a new class of heterocyclic analogues of crystal violet dyes.
Deep purple: By the transformation of readily available N,N-disubstituted 2-aminothiophenes and 2-aminothiazoles into heterocyclic analogues of Crystal Violet, such as, tris(2-dimethylamino-5-thienyl)methinium prechlorate (cation shown), the series of dyes derived from these heterocyclic structural units as the important chromophoric component is significantly extended and a gap in the class of heteroanalogous triphenylmethane dyes has been closed.
