Descripción
Steady-state and time resolved luminescence quenching measurements of (2T/2E)Cr(phen)33+ were used to investigate the association of phenols to sodium dodecyl sulfate (SDS) micelles. Steady-state results show the quenching process occurs in the micellar pseudo phase. Scatchard plots indicate that the process is a partition between aqueous and micelles. The k+ and k− rate constant have been evaluated from time resolved data and the binding constants were obtained. The trend found in the K’s were 4-H-Ph < 2,6-diMe-Ph < 4-Br-Ph.We concluded that it is possible to use *Cr(phen)33+ as a luminescent probe to determine association parameters for  quenchers to micelles of SDS.
