Abstract The synthesis and mesomorphic properties of several new series of liquid crystalline materials are described. These include two novel diacetylenic structures, 4,4′-di-n-acyloxydiphenyldi-acetylene and the unsymmetrical 4-n-alkoxy, 4′-cyanodiphenyldiacetylene, and the analogous 4-n-alkoxy,4′-cyanotolanes and stilbenes. A discussion of the effect of structure on transition temperatures is included.
