Abstract
A new liquid crystalline structural class has been observed. The synthesis and mesomorphic properties of the novel diacetylenic liquid crystals, 4,4′-di-n-alkyldiphenyldiacetylenes and 4,4′-di-n-alkoxydiphenyldiacetylenes are described. In addition, an improved synthesis of the key intermediate, 4,4′-dihydroxydiphenyldiacetylene, has been developed.Keywords
