This work was carried out as part of a project to find novel thermotro
pic low temperature liquid crystals [1]. The biphenyl based material w
as chosen so as to confirm or deny the widely held belief that additio
n of a second oxygen in a terminal chain destabilizes the mesophase. T
he results were unexpected as they yielded the first recorded incidenc
e of the formation of the crystal K phase directly on cooling from the
isotropic melt.
