This report results from a contract tasking Ben-Gurion University of the Negev as follows The Contractor proposes to investigate the possibility of reversibly tuning the conductivity and linear and nonlinear optical properties of conjugated chains via protonation. Protons, the smallest chemical species, are generally mobile. and hence offer the potential for reversibility. Equally importantly the concepts proposed herein do not rely on as strongly on redox chemistry. but rather on acid-base chemistry. This may produce species more stable than those produced by addition of powerful oxidizing agents and not be as harmful to the polymer structure. Finally the principles outlined will be used to explore charge pumping and control in these materials. The principal methods to be used synthesis of conjugated systems, their UVVis and NMR analysis under various acid-dopants and conditions, and computational chemistry to support and rationalize the results.
