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, 1 H 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.
