The structure of (2,2,3,3,4,4,4-heptafluorobutyloxycarbonyl)]phenyl 4-
undecyloxybenzoate, C29H33F7O5, adopts a slightly bent conformation. M
olecules are aligned in the same direction and orientation as in an S-
A smectic-like molecular arrangement. It is, therefore, a precursor of
a ferroelectric phase.
