PHOTOINDUCED CHARGE TRANSFER REACTION OF BENZOPHENONE WITH AMINE IN VESICLES

Institute of Photographic Chemistry, Academia, Sinica, Beijing 100101

Received Date: 19 February 1993

Photoinduced charge transfer reaction of benzophenone (BP) with, amine was carried out in the vesicles of dicetyldimethylammonium bromide (DCDAB) over wide ranges of amine concentration (0.01~4.0M).Linear plots of φ^-1 vs.[TEA]^-1 at low concentration of amine (<0.02M) and Ø^-1 vs.[TEA]^-2 at high concentration were obtained.Kinetic data demonstrate that the electron transfer is promoted significantly by DCDAB vesicles and proton transfer becomes more efficient at high amlne concentrations, leading to a decrease of Kd/Kr and increase of Kh/Ke.The kinetic expressions of photoreaction of BP bound to DCDAB bilayer are developed.
