Abstract
Two closely related amphiphilic compounds have been deposited as multilayers by evaporation in vacuo, the structures of which have been studied as a function of time using low-angle X-ray diffraction and polarising microscopy. The material consisting of the shorter of the two molecules forms a structure in which the repeat unit corresponds to a monolayer but, initially, there are two phases present with slightly different d spacings. At room temperature this material reorganises over a period of 1 week so that it consists entirely of one of these phases. The material consisting of the longer molecule forms a structure in which the repeat unit is a bilayer (a Y structure). On storing for 1 week at room temperature the first-order Bragg peak disappears but the second-and third-order Bragg peaks remain. A possible explanation for this remarkable behaviour is proposed.
