SYNTHESIS OF 2 NEW HYDROGEN-BOND INDUCED LIQUID-CRYSTALS

Two new hydrogen bond induced liquid crystals with 4-butoxy benzoic acid as the proton donor and two chiral substituted stilbazole as the proton acceptor have been synthesized. Their liquid crystal transitions were studied by DSC and optical polarized microscope, the IR spectra of the complexes show the existence of the intermolecular hydrogen bond. The results of DSC and optical polarized microscope show that one of them (4BA-VSZ) has a chiral smectic C phase.
