The synthesis and study of several surfactant trans-stilbene derivatives are described.Both compounds containing the trans-stilbene at the hydrophobic terminal of a surfactant chain and those containing an intrachain stilbene chromophore have been studied

The Norrish type II photoprocess of surfactant keto acids has been used to examine the relative environment of the ketons in certain organized media.Values for φ of 0.81 in SDS micelles and 0.72 in CTAC micelles were obtained for 1, which are intermediate between the value of 0.29 in benzene and 1.0 in tert-butyl alcohol.The ketone thus experiences a fairly hydrophilic environment in micelles.Addition of heptanol to SDS micelles containing 2 causes a decrease in φII values, suggesting that a more hydrophobic region is seen by the ketone, possibly owing to water expulsion from the micelle.Incorporation of 1 into dioctadecylmethylammonium chloride (DODAC) vesicles on irradiation gives values similar to those of a benzene-like medium below the phase-transition temperature, and the φII values slowly increase as the temperature increases.Multilayer assemblies of 1 exhibit very little type II reactivity when irradiated, having values φ II.
