Abstract
The association equilibrium of three 10-N-alkyl derivatives of acridine orange in aqueous solution has been studied spectrophotometrically. The ΔFD, ΔHD, and ΔSD of dimerization have been computed through the experimental light absorption spectra.
The results are in favour of the assumption that hydrophobic interactions play a relevant role on the dye stacking in aqueous solution.
