Synthesis and Mesomorphic Properties of Diphenyl- and Biphenylyl-pyrimidines

Abstract

Abstract The synthesis and mesomorphic properties of four classes of cyano-substituted diphenyl -and biphenylyl-pyrimidines are reported. The new compounds are colourless, chemically and photochemically stable and have wide mesomorphic ranges. The synthesis of one member of each homologous series is described in detail.
