A hexagonal columnar phase formed in lateral fluorinated bent-shaped molecules based on a 1,7-naphthalene central core

Abstract

Lateral fluorinated bent-shaped molecules based on a 1,7-naphthalene central core and alkoxy tails can form a switchable hexagonal columnar phase and B₄ phase. The columnar phase has a large two-dimensional hexagonal lattice of 65–70 Å and exhibits ferroelectric switching with spontaneous polarization along the column axis.
