Abstract
A promising approach for synthesizing stable n-doping polymers is to alternate electron donating and electron accepting moieties along a conjugated polymer backbone. The donors and acceptors used can be chosen to tailor the properties of the resultant polymer to achieve a low band gap or to increase solubility. This research focuses on the use of thiophene and 3,4-ethylenedioxythiophene donor groups in conjunction with a variety of heterocyclic nitrogen-containing derivatives as acceptors. The high nitrogen heterocycles increase the electron affinity of the polymer while the alternation of the donor and acceptor groups increases conductivity. The monomers are synthesized using transition metal mediated coupling reactions and characterized using nuclear magnetic resonance spectroscopy (NMR) techniques.
