Abstract

The formation of liquid crystals of β,γ-distearoylphosphotidylcholine (DSPC) in N-ethylammonium nitrate, a low-melting fused salt, has been documented with polarizing microscopy and small-angle X-ray scattering. The Lβ′ → Pβ′ → Lα transitions with increasing temperature are present in analogy with the behavior of DSPC in water. For a 1:1 (by weight) mixture the d spacing for the Lα phase is 63 Å and the surfactant head group area is 76 Å2.
