Effects of the Central Unit Structure, Lateral Substitution and Symmetry on the Mesomorphic Behavior of Some Bent‐Core Azoester Derivatives Open
We report here the synthesis and characterization of some new bent‐core asymmetric compounds derived from resorcinol whose thermal behavior has been analyzed by comparison with their analogs derived from 1,3‐disubstituted benzene and 2,7‐d…

Mesomorphic and Thermal Behavior of Symmetric Bent-Core Liquid Crystal Compounds Derived from Resorcinol and Isophthalic Acid Open
Bent-core liquid crystals (BCLC) have been widely studied as a result of their unusual polar and chiral properties. Similar to calamitic and discotic molecules, BCLC molecules also exhibit nematic phases, besides other higher order mesopha…

DIELECTRIC PROPERTIES OF SOME BENT CORE LIQUID CRYSTALS Open
Dielectric measurements were carried out on a series of bent-core liquid crystals based on resorcinol and 2, 7-dihydroxinaphtalene cores and presenting B mesophase in between 30-160°C.The dielectric constants in the liquid crystalline phas…
