Mesomorphic properties of 5boSOMH from new three rings thiobenzoate series

Phase polymorphism of a novel chiral liquid crystalline compound (S)-(+)-4-{4-(4-n-pentylbicyclo[2,2,2]octancarbonylthio)benzoyloxy}benzoate 1-methylheptyl (in short: 5boSOMH) was examined with three complementary methods: Differential Scanning Calorimetry (DSC), Polarized Light Optical Microscopy (POM) and Transmitted Light Intensity (TLI). X-Ray diffraction was used to learn about molecular arrangement in ordered phases. 5boSOMH has two enantiotropic phases: SmB* and SmA*, and exhibits solid phase polymorphism.
