日期:——
A homologous series of the new N-heterotolane was synthesized using two cross-coupling reactions mediated by copper and palladium/copper. The final compounds present a naphthyl-pyridyl framework connected by an acetylene group. The evaluation of physico-chemical properties is described. All the compounds exhibit the smectic A mesophase.
