This thesis describes studies on the palladium catalyzed synthesis of imidazole-containing п-conjugated polymers. Recent research in our laboratory has found that these polymers can be prepared in a single step, and directly from di-imines, di-acid chlorides and simple imines. In chapter 2, we describe the development of a highly active catalyst for this polymerization. This can operate at as low as 0.5 mol% palladium catalyst, and provides a route to synthesize these polymers on gram scale. In addition, several issues affecting polymerization were identified, including the termination of polymer growth by attack of sulfinic acid on in situ generated Münchnones. Attempts were made to inhibit this termination. The issue of solubility o...
