Hydrogen Bonded

A new series of supramolecular hydrogen-bonded liquid cryatals complexes were synthesized based on pyridine derivative and 4-n-alkoxybenzoic acids. The formation of hydrogen bonds was verified by infrared spectra. The thermal behavior of supramolecular liquid crystals was studied using differential scanning calorimeter (DSC). The liquid crystal texture was revealed with polarizing optical microscope (POM). It demonstrats that all supramolecular complexes have good liquid crystal properties.
