Synthesis, transition temperatures and some physical properties of some low-melting smectic materials
As part of a systematic study of the factors affecting the smectic C phase, a dipole (ie., an oxygen atom) was introduced into the middle of one of the (non-polarisable) alkyl chains of a model phenylpyrimidine. A carbon-carbon double bond has also been i
