Expedient new routes to molecular and polymeric materials for applications in organic electronics

Abstract

This thesis describes the development of synthetic techniques to produce two types of organic electronic materials. The first are benzodipyrrolidone-based polymers (BDP) since these have very low band gap energies and high charge transport mobilities, ideal for organic transistors. A synthetic route to access the BDP core monomer was proposed involving two key steps, a Pummerer type cyclisation reaction and a nickel catalyzed cross-coupling step. The second are new pyrrolopyridinedione based polymers (PPyD). This novel core was synthesized using a very short route involving an Inverse Electron Demand Diels-Alder cyclisation reaction. The first of these projects involves demonstrating the versatility of the Pummerer cyclisation and producing a library of BDP based monomers with novel structures, which have the potential to be polymerized giving new and useful organic electronic materials. The second project involves synthesising a library of novel PPyD based polymers and exploring their applications in organic electrochromic devices.
