PHOTOCHEMICAL-REACTION OF ARYLMETHYL SULF ONE IN MICROEMULSIONS

The photochemical reactions of benzyl p-methylbenzyl sulfone (ASO(2)B) in sodium dodecylsulfonate (As)-pentanol-H2O microemulsions and lyotr ipic liquid crystals have been studied. The effects of microenviroment s provided by microemulsion and lyotripic liquid crystal on product di stribution have been investigated. While W / O emulsion gave a cage ef fect analogoues to pentanol, the lyotripic liquid crystal and O / W em ulsion provided supereages. This results were explained by considerati on of the hydrophobic of the sulfone and the structure of the reaction media. Application of a weak external magnetic field to the photochem ical reaction of ASO(2)B in O / W microemulsion leads to a decrease in cage effect, suggesting that the photochemical reaction proceeds via a triplet excited state.
