Dielectric and electro-optic studies of a bimesogenic liquid crystal composed of bent-core and calamitic units
VIJ, JAGDISH; PANOV, VITALI (2014)A bimesogen, BR1, composed of a bent-core and calamitic unit, linked laterally via a flexible spacer is investigated by dielectric and electro-optic techniques. X-ray results show the presence of clusters in the nematic ... -
Effect of cybotactic clusters on the elastic and flexoelectric properties of bent-core liquid crystals belonging to the same homologous series
VIJ, JAGDISH; PANOV, VITALI (2013)We report results of the splay ( K 11 ) and bend ( K 33 ) elastic constants and the effective flexoelectric coefficient of three bent-core liquid crystals belonging to a homologous series of 4-cyanoresorcinol ... -
Field-induced periodic chiral pattern in the Nx phase of achiral bimesogens
VIJ, JAGDISH; PANOV, VITALI (2012)Some hydrocarbon-linked mesogenic dimers are known to exhibit an additional nematic phase (Nx) in the temperature range below the conventional nematic (Nu) phase. One of the features of this phase is the presence of optical ... -
Short-range correlations seen in the nematic phase of bent-core liquid crystals by dielectric and electro-optic studies
VIJ, JAGDISH; JANG, YUN; PANOV, VITALI; KOCOT, ANTONI (2011)Three bent-core nematic liquid crystals having the same core but with different terminal groups, short (C4) and long (C7,C9) tails, are investigated by dielectric and electro-optic contrast spectroscopic techniques. C4 ... -
Sign reversal in the dielectric anisotropy as functions of temperature and frequency in the nematic phase of a bent-core mesogen
VIJ, JAGDISH; JANG, YUN; PANOV, VITALI (2010)The sign reversal in the dielectricanisotropy(???????) from positive to negative is observed for 4-cyanoresorcinol bisbenzoate system with temperature and frequency in the nematic phase of a bent-core system as the temperature ...
