Three new cationic amphiphiles bearing anthraquinone moieties at the polar headgroup region were synthesized. The single-chain amphiphile, N, N-dimethyl-N-octadecyl-N-(9, 10- dihydro-9, 10-dioxoanthracen-2-ylmethyl) ammonium bromide 1, in the presence of cetyltrimethylammonium bromide upon dispersion in water gave co-micellar aggregates containing covalently attached anthraquinone residues at the polar aqueous interfaces. ...
