M. Imperor-clerc et al., Phase transition between single crystals of two thermotropic cubic phases from a mixture of 3,5-didodecyloxybenzoic acid and C-18-ANBC, CHEMPHYSCHE, 2(8-9), 2001, pp. 533
A reversible phase transition between two different thermo-tropic cubic pha
ses is observed in a mixture of two carboxylic acids. Such a transition was
characterised by single-crystal X-ray diffraction and direct optical micro
scopy; an image of a facetted droplet just at the transition between the tw
o phases is shown in the picture.
