摘要: Abstract Liquid crystal phases (LCs) formed by achiral bent-core molecules (banana LCs) are distinguishable from those of their classical (i.e., rod/disc-shaped) counterparts with only quadrupolar order. We argue that the interplay between tetrahedratic (octupolar) and order clarifies physics banana LCs sufficiently to account for two effects observed in LCs: a 100 times larger field-induced anisotropy than ambidextrous chirality where left- right-handed chiral domains co-exist.
