On the impact of aromatic core fluorination in hydrogen-bonded liquid crystals.

ABSTRACT: Herein we report the impact of fluorine substitution on the liquid crystalline (LC) self-assembly of supramolecular hydrogen-bonded rod-like architectures. This was systematically investigated by introducing fluorine atom at different positions or with different numbers on the investigated supramolecules. Therefore, eight different groups of hydrogen-bonded LCs (HBLCs) were designed and synthesized in which four 4-hexyloxybenzoic acid derivatives without or with fluorine substitution were used as proton donors. The proton acceptors are fluorinated or nonfluorinated alkyloxyazopyridine derivatives. The hydrogen bond formation between the complementary components was proved using FTIR and ¹H NMR spectroscopy. All HBLCs were investigated for their mesomorphic behaviour using variou
