Ion polarisation-assisted hydrogen-bonded ferroelectrics in liquid crystalline domains.

ABSTRACT: An alkylamide-substituted (-NHCOC₁₀H₂₁) hydrogen-bonded dibenzo[18]crown-6 derivative (1) was prepared to stabilise the ionic channel structure in a discotic hexagonal columnar (Col_h) liquid crystal. The introduction of simple M⁺X^- salts such as Na⁺PF₆ ^- and K⁺I^- into the ionic channel of 1 enhanced the ionic conductivity of the Col_h phase of the M⁺·(1)·X^- salts, with the highest ionic conductivity reaching ∼10^-6 S cm^-1 for K⁺·(1)·I^- and Na⁺·(1)·PF₆ ^- at 460 K, which was approximately 5 orders of magnitude higher than that of 1.
