Smectic liquid crystals with âde Vries-likeâ properties are characterized by a maximum layer contraction of â¤1% upon transition from the orthogonal SmA phase to the tilted SmC phase. We show that binary mixtures of âde Vries-likeâ and conventional SmC mesogens with a molecular length ratio of 1.34 undergo a SmAâSmC phase transition with a maximum layer contraction ranging from 1.0 to 1.9% depending on the mixture composition.
