The spontaneous formation of a chiral phase via molecular recognition in a system consisting of achiral components is reported. Specifically, the liquid crystalline behaviour of two molecular complexes assembled by hydrogen bonding between a stilbazole-based template and alkoxybenzoic acids has been characterised. The complexes exhibit the heliconical twist-bend nematic phase (N_TB) over a broad temperature range despite the hydrogen-bond acceptor not being liquid crystalline and the donor exhibiting the conventional achiral nematic phase.

通过混合非手性组分的自发手性：扭曲弯曲的向列相，由不同组分之间的氢键驱动†

据报道，在由非手性组分组成的系统中，通过分子识别可自发形成手性相。具体地，已经表征了通过基于斯蒂巴唑的模板与烷氧基苯甲酸之间的氢键键合而组装的两种分子配合物的液晶行为。尽管该氢键受体不是液晶的并且该供体表现出常规的非手性向列相，但该络合物在很宽的温度范围内仍表现出螺旋扭曲-向列相（N _TB）。
