Reversibly tunable helicity induction and inversion in liquid crystal self-assembly by a planar chiroptic trigger molecule.
Reversible control of the helical pitch length and inversion of helical handedness in an induced cholesteric liquid crystal phase were accomplished via a combination of photochemical and thermal isomerizations of a planar chiral azobenzenophane molecule.
