The aniline trimer at the emeraldine oxidation state, N, N'–bis(4'-aminophenyl)-1,4-quinonenediimine, has been synthesized via an oxidative coupling method developed in our group. Resent research efforts have been made to find suitable conducting oligomers for nano size electronic devices using this aniline oligomer. Our recent work involves substitution modifications of the above trimer oligomer in two ways: 1) by introducing n-alkyl chain(s) to the terminal amine ends of the trimer in an effort to make potential electroactive surfactant molecules; 2) by introducing thiol group(s) to one or both terminal amine ends, which may be useful in making electronic nanojunctions. An alternate method for making substituted trimers has also been implemented by using cross coupling aromatic substitution using N, N'-dichloro-1,4-benzoquinonediimine and N,N-disubstituted aniline compounds. This method may represent an economical and convenient route to N-alkyl and N-alkyl thiol substituted oligoaniline molecules.
