Discussed is the synthesis of electron-rich, aromatic thiophene derivatives and their incorporation as components in donor-acceptor columnar liquid crystals (DACLCs). The addition of thiophene derivatives to the previously studied electron-donor aromatic series, offers potential improvements to the stability and optoelectronic properties of these materials. The synthesis, specifically of thio-benzene and naphthalene derivatives, accomplished via a halogen/triflate-selective Sonogashira coupling with 1-octyne, followed by a nucleophilic aromatic substitution, to add the sulfur and form the aromatic heterocycles. Furthermore, the subsequent DALCL materials and their initial characterization will be discussed.
