Abstract

Novel liquid-crystalline N,N′-diarylsquaramides 1a and 1b were designed and synthesized, and their properties were elucidated. The squaramides exhibited thermotropic columnar liquid-crystalline phases at low temperature including room temperature. X-ray crystallographic analysis of methoxy derivative 1c showed the self-assembly of face-to-faced dimer through π-π interaction.
