Synthesis and thermodynamical interactions of (S)-5-(2-methylbutoxy)-2-[[[4-hexyloxyphenyl]imino]methyl]-phenol liquid crystal with some solvents

Abstract

Liquid crystalline compound (S)-5-(2-methylbutoxy)-2-[[[4-hexyloxyphenyl]imino]methyl]-phenol (MBHOPIMP) has been prepared and characterized. Phase transition temperatures of MBHOPIMP were determined by polarizing microscopy, differential scanning calorimetry. The retention diagrams of octane, nonane, cyclopentane, cyclohexane, ethyl acetate, butyl acetate, iso-butyl acetate, benzene, toluene, ethylbenzene and chlorobenzene on MBHOPIMP were plotted at temperatures between 110 and 130 degrees C by inverse gas chromatography technique. Then, specific retention volume, V-g(0), Florry-Huggins polymer-solvent interaction parameter, chi(infinity)(12), hard-core polymer-solvent interaction parameter, chi(12)* and effective exchange energy parameter, X-eff were determined.
