The adsorption of N-alkylated acridine orange derivatives (AO-C{sub n}; n = the number of carbon atoms in an alkyl group) by colloidally dispersed zirconium phosphate (ZrP) was studied by spectrophotometry and electric dichroism. An AO-C{sub n} cation was bound to ZrP by releasing a proton in the phosphate group of ZrP. The electronic spectrum of bound AO-C{sub n} showed that the dye cations formed an aggregate on the polymer. The reduced linear dichroism of a bound dye molecule, {rho}, was determined as a function of n: {rho} = 1.3-1.0 for n = 0-2, while {rho} = {minus}0.3 to {minus}0.4 for n = 3-9.
