Abstract
The temperature T-m characterizing the gel to liquid crystalline trans ition in vesicles formed from dialkyl phosphates increases with an inc rease in alkyl chain length for phosphates with two identical alkyl gr oups. The temperature T-m also depends on the counter cation. Calorime tric data are interpreted in terms of cooperative melting in domains c haracterized by patch numbers. The scans recorded by differential scan ning microcalorimetry show two or more extrema where the alkyl chain l engths differ.
