Temperature dependence of solvation dynamics in a micelle. 4-Aminophthalimide in Triton X-100

Sen P, Mukherjee S, Haider A, Bhattacharyya K

Solvation dynamics of 4-aminophthalimide (4-AP) is studied in a Triton X-100 (TX) micelle at three different temperatures. The average solvation time has been found to be 800, 400 and 110 ps at 283, 303 and 323 K, respectively. This corresponds to an activation energy of 9 +/- 1 kcal mol(-1). The observed temperature dependence is in qualitative agreement with recent computer simulations on the solvation dynamics in micelles. (C) 2004 Elsevier B.V. All rights reserved.
