Twist Grain Boundary Phases in Proper Ferroelectric Liquid Crystals Realm
Advanced Science, EarlyView.A new type of twist‐grain‐boundary (TGB) phases, with a periodic, helical arrangement of ferroelectric smectic blocks, are reported, formed by molecules with giant longitudinal dipole moment. They emerge below the antiferroelectric smectic phase, and their structure is governed by electrostatic interactions amplified by weak chiral forces.
