Abstract

Five new chiral liquid crystal systems induced by intermolecular hydrogen bonding between 4-[(s)-2-chloro-3-methyl]butyroyloxy-4′-stilbazole (MBSB, proton acceptor) and 4-alkoxybenzoic acids (nBA, proton donors) were prepared. Their liquid crystalline properties were investigated by DSC and polarized optical microscopy. Chiral nematic and chiral smectic phases were observed, and the thermal stability of one complex was studied through temperature dependent infrared spectroscopy.
