CPL-active water-soluble aromatic oligoamide foldamers.

A series of enantiopure water-soluble quinoline-based foldamers were prepared and their optical and chiroptical properties in water were investigated. The new hexameric sequences incorporated either cationic or anionic water-solubilizing chains, and one of the oligomers was additionally functionalized by an electron donating moiety to further modulate the optoelectronic properties. A systematic study revealed strong electronic circular dichroism and circularly-polarized luminescence properties in water, with dissymmetry factors up to 2 × 10
