Syntheses and Structures of Pseudo-Mauveine Picrate and 3-Phenylamino-5-(2-Methylphenyl)-7-Amino-8-Methylphenazinium Picrate Ethanol Mono-Solvate: The First Crystal Structures of a Mauveine Chromophore and a Synthetic Derivative

Abstract

Pseudo-mauveine picrate and a synthetic derivative of mauveine, 3-phenylamino-5-(2-methylphenyl)-7-amino-8-methylphenazinium picrate, have been prepared via their leuco-bases and their crystal structures determined. Time-dependent density functional theory gives a good match for the calculated and measured UV-Vis spectra.
