Abstract

A series of alkyl N,N-disubstituted aminophenylazo-4-benzoates were prepared from the reactions of an acyl phenylpiperazine with a series of the diazonium salts. The mesogenic behaviours of the resulting dyes were studied by polarizing optical microscopy and differential scanning calorimetry. Single crystal structure determination, powder XRD, and molecular modelling of a representative compound were also undertaken to understand the relative structural conformation.
