Semiconducting polymers based on charge‐transfer complexes. I. Synthesis of electron‐donor‐containing poly‐N‐acylethylnimines

Polymers were made which contained 10‐methyl, 3‐phenothiazinyl, and 4‐(methylthio)phenoxy electron‐donating groups on side chains. N‐Acyl‐substituted poly‐ethylenimines were chosen because the repeat distance along the polymer chain is the same as the repeat distance in most aromatic charge‐transfer complexes (about 6.4 Å) and the side chains do not interfere with each other. This paper describes synthetic routes for preparation of these electron‐donor‐containing polymers. Synthesis of a polyacrylate donor is also described.
