Abstract:
Smectic liquid crystals with 'de Vries-like' properties are characterized by a maximum layer contraction of ≤1% upon transition from the non-tilted SmA phase to the tilted SmC phase. We show herein that one can systematically increase the 'de Vries-like' character of a smectic liquid crystal by tuning the frustration between SmA- and SmC-promoting elements according to established structure-property relationships.
