Two new hydrogen bond induced liquid crystals with 4-butoxy benzoic ac
id as the proton donor and two chiral substituted stilbazole as the pr
oton acceptor have been synthesized. Their liquid crystal transitions
were studied by DSC and optical polarized microscope, the IR spectra o
f 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.
