Synthesis, Mesomorphic Properties and Application of (R,S)-1-Methylpentyl 4′-Hydroxybiphenyl-4-carboxylate Derivatives

Thirteen new liquid crystalline racemic mixtures were synthesized and investigated. For these mixtures, the phase sequences their changes determined by polarizing optical microscopy (POM). The transition temperatures enthalpies checked differential scanning calorimetry (DSC). All racemates have an anticlinic smectic CA in a broad temperature range. Three highly tilted antiferroelectric doped with six at concentration of 20% weight. helical pitch prepared was measured spectrophotometry method. longer than base mixtures.
