Generation of a Chiral Giant Micelle

摘要: Over the past few years, chiral supramolecular assemblies have been successfully used for recognition, sensing and enantioselective transformations. Several approaches are available to control chirality of discrete (e.g., cages capsules), but efficient in assuring micellar aggregates. Optically active amino acid-derived surfactants commonly generate spherical micelles. To circumvent this limitation, we benefited from uniaxial growth micelles into long cylindrical usually called wormlike or giant micelles, upon addition cosolutes. This paper describes unprecedented formation aqueous solutions cetyltrimethylammonium bromide (CTAB) increasing enantiopure sodium salt 1,1′-bi-2-naphthol (Na-binaphtholate) as a cosolute. Depending on concentrations CTAB Na-binaphtholate, gel-like systems obtained. The transition str...
