Abstract
In this communication, we report the synthesis and ring‐opening metathesis polymerisation (ROMP) of a 5‐substituted cyclooctene‐derivative, (±)‐cis‐[11‐(4′‐cyanobiphenyl‐4‐yloxy)undecyl]cyclooct‐4‐enecarboxylate. A highly active molybdenum‐carbene was used as initiator. The prepared polymer is liquid crystalline and shows a nematic phase between −5 and 53°C.
