Synthesis and Property of Liquid Crystal Compounds: α-Methyl biphenyl esters
Abstract:
Two series of α-methyl biphenyl esters, series PBM and series PMB including tweleve compounds were synthesized. All these compounds are liquid crystals with low melting points due to the α-methyl stereo-effect. There are very wide smectic C(Sc) or chiral smectic C(Sc*) liquid crystal phase ranges in the PBM series compounds, but narrow phase ranges in the PMB series where the α-methyl is in the central part of the molecular chain. The chemical structures of the compounds were verfied by IR, 1H NMR, MS spectra and elemental analysis. Their transition temperatures of liquid crystal phase and phase states were verified by DSC and POM. They could have promising applications especially as components in the ferroelectric liquid crystal display.
