Keywords: bent-coreliquidcrystals; biaxiality; clusters; dielectric spectroscopy; Introduction
Biaxial liquid crystals (LCs) exhibit supramolecular structures with long-range orientational ordering of the long and the short molecular axes but without a long
. This also narrows the distribution in the cluster size as shown by a decrease in α1 with decreasing temperature.
Conclusion
We investigated two nematic bent-coreliquidcrystals with the same mesogenic core and molar mass but with different alkyl terminal groups terminated by: (i) symmetrical C6H13 and
