Optical, DSC and X-ray studies show that C-n H2n+1 O C-m H-2m OH (n =
16; m = 4; n = 18 and 20, m = 2 and 3; n = 22, m = 3) /aqueous H3PO4 s
ystems exhibit mesophases in the order middle - viscous isotropic - la
mellar - gel. The low temperature gel displays characteristically the
chevron pattern due to an undulation instability of bilayers; it is po
ssibly caused by hydrocarbon chain elongation and stiffening.
