Synthesis of soluble main-chain poly(quinolines)

Polyquinoline polymers incorporating a bisquinoline moiety along their polymeric backbones have been synthesized and fully characterized. Two different macromolecular architectures were created; either fully conjugated or rigid-flexible main chains with both cases showing improved solubilities in common organic solvents. The monomers' and subsequent polymers' initial characterization was performed by NMR, as well as GPC and DSC techniques. Additionally, the polymers optical properties were evaluated using UV-Vis and PL spectroscopies. Cyclic voltammetry measurements provided information on the electrochemical properties and energy levels (HOMO-LUMO) of the final polyquinolines in order to determine possible applications in electronic devices.
