Abstract

New cholesteric liquid crystals induced by intermolecular hydrogen bonding between 3-cholesteryloxycarbonylpropanoic acid (MCB) and 4-(4-alkoxybenzoyloxy)-4ʹ-stilbazoles (nSZ); between MCB and N-(4-pyridylmethylidiene)anilines (n-PMA) were prepared. Their liquid crystalline properties were investigated by DSC, polarized optical microscopy and X-ray diffraction. Cholesteric and smectic phases were observed. In order to study the influence of covalent and non-covalent bonding upon the liquid crystal behaviour several new covalently bonded N-[4-(3-cholesteryloxycarbonylpropionyloxy)benzylidiene]-4-alkoxy anilines were investigated.
