Pyrene Solubilization from H2O/DMF Solvent Mixture to the "Crew cut" Micelles of Polystyrene-Polyacrylic Acid Diablock Copolymer*
A method of calculation of the amount of pyrene absorbed from the fluorescence emission spectrum has been developed. By this method the solubilization of pyrene from H2O/DMF solvent mixture to the crew-cut micelles of polystyrene-b-polyacrylic acid diblock copolymer has been investigated. The results showed that the solubilization of pyrene depends strongly upon water content in the solvent mixture. The amount 0f pyrene absorbed was enhanced with increasing the water content. The absorption isotherms were calculated and discussed by combination of the formula developed and the partition coefficient Kv. The theoretical treatment suggested an approach to calculate Kv directly from the intensity values measured experimentally.
