Effect of polyion conformation on dye binding. V. Induced optical activity of acridine orange bound to a synthetic nonstereoregular polyelectrolyte

Abstract

AbstractIt is shown that the induced Cotton effects in the visible region of the absorption bands of acridine orange in the presence of a nonstereoregular α‐carboxylic polysulfonamide (PLL) can be attributed to stacked bound dye molecules, irrespective of the conformation of the polymer. The existence of an ordered structure seems to be unnecessary for such an induction.
