Benzylhexadecyldimethylammonium chloride (BHDC) micelles in water are very similar to their cetyltrimethyl ammonium bromide (CTAB) counterparts with respect to (1) nature of the micelle surface and polarity (pyrene and pyrene carboxyaldehyde measurements); (2) micelle aggregation number and size; and (3) nature of photochemical reactions centered on the micelle. NMR data indicate that the benzyl group of BHDC interacts with the head group region of the micelle and that the phenyl ring is not pushed into the micelle interior. The benzyl group does not affect the environment of pyrene on the micelle, which is similar to that on CTAB. Reversed micelles of BHDC in benzene have properties characteristic of other reversed micelle systems. This is borne out by the nature of the water pool in the BHDC which shows that the properties of bulk water are approached only when water in excess of that necessary for surfactant solvation is present. The benzyl group in these micelles is placed away from the water phase and between the surfactant head groups. The micellar sizes are similar to those reported for AOT reversed micelle systems. 37 references.
