Synthesis and characterization of bent-rod liquid crystals

Two series of diesters with bend-rod shapes were synthesized and their thermal properties characterized by POM and DSC. The central group conformational mobility and polarity as well as the length of the mesogenic groups were varied in order to correlate these parameters with mesophase stability. Results indicate that series II diesters are enantiotropic and that their mesophase sensitivity to central group structural changes is limited.

Photo and electrically switchable B7 mesophase exhibiting asymmetric bent-core liquid crystals

The first bent-core liquid crystal materials with a photo-active azo linkage exhibiting the B7 mesophase are reported. The lower homologues of the bent-core compounds display the B1 phase and higher homologues show the B7 mesophase. The mesomorphic properties were characterized using polarized optical microscopy, differential scanning calorimetry and X-ray diffraction. The B7 phase of these materials establishes ferroelectric switching characteristics with anticlinic organization (SmCAPF) of the molecules in the layers. The bent-core molecules with an azo linkage are important for photoisomerization studies, which indicate trans to cis isomerization at 30 s, whereas the reverse processes take place over 40 s in chloroform.

Synthesis and optical properties of luminescent naphthalene-based liquid crystals

Luminescent naphthalene-based liquid crystals were newly synthesized and changes of the luminescent color through the phase transitions were characterized. We prepared the compounds by combining naphthalene and known mesogenic cores, oxadiazole and fluoro
