Abstract
Unsymmetrical dimesogenic compounds with cholesteryl and 4-(trans-4-n-alkylcyclohexyl)phenoxy parts were synthesized by condensation of cholester-3-yl 6-bromohexanoate with appropriate 4-(trans-4-n-alkylcyclohexyl)- phenols. Structures and thermal phase behaviour of these dimesogenic compounds have been confirmed by IR, 1H NMR, elemental analysis, DSC, polarity microscopy and XRD measurements. Their thermal phase behaviour was significantly different with that of other cholesterol-based dimesogens while they exhibited low and wide phase transition temperature.
