The polymers presented in this paper are designed for the intended use in light-emitting diodes. The synthesis of a new series of macromolecules containing isolated oligothiophene, oligothienylene vinylene, or bithiazole conjugated units bridged by aliphatic units is presented along with optical characterization by W-vis absorption and fluorescence spectra in solution. These polymers gave very similar optical traits to their corresponding subunits while possessing the physical characteristics of a macromolecule.
