"Schematic description of (a) the molecular order in isotropic liquids (no order), in (nematic) liquid crystals (displaying only orientational order) and in crystalline solids (featuring both orientational and positional orders); (b) a solute embedded in a chiral polymer-based LLC with a phase director, n, aligned with B0 in the laboratory frame (X, Y, Z). The solute alignment can be described by using an axis system attached to the molecule (a, b, c); and (c) stretched and compressed gels inducing a molecular order with respect to B0.
