PERNAK, Juliusz et al. Long alkyl chain bis-quaternary ammonium-based ionic liquids as biologically active xanthenes dyes. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.5, pp. 839-845. ISSN 1678-4790.

New examples of air-and moisture-stable, hydrophobic and hydrophilic bis-quaternary ammonium derived ionic liquids have been prepared. These ionic liquids have been proposed to act as biological active dyes with characteristic unique physicochemical properties, providing alternatives to some conventional anionic xanthene dyes such as eosine Y, fluorescein and erythrosine.

Palabras clave : ionic liquids; xanthene dyes.
