Light-induced director reorientation through the electroclinic effect and optic axis rotation in a chiral smectic A
Abstract:
We report the observation of light-induced director reorientation under the application of an electric field in a chiral smectic A liquid crystal owing to the temperature dependence of the electroclinic coefficient. We also demonstrate the occurrence of another light-induced phenomenon that leads to optic axis rotation, whose origin is not yet clear. Finally, we show that thermal indexing cannot be neglected when fitting the experimental data.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
