Abstract

We have synthesized rod-shaped tricyclic monoazo and bisazo dyes based on amino derivatives of arylpyrimidines and N,N-dialkylanilines or p-nitroso-N,N-dialkylanilines. We have shown that the process of azo coupling of the diazonium salt obtained from 2,5-bis(p-aminophenyl)pyrimidine is accompanied by dediazoniation, with substitution of the diazonium group by hydrogen or an aryl group. The monoazo dyes obtained display mesomorphic properties which are absent in the bisazo dyes.
