Description
Tsubasa Mikie and co-authors report a design shortcut for plastic electronics in this 2026 chemistry paper. Polymers that carry electric charge well usually need fused rings locked into the backbone, but this team reached high performance without any fused rings.
They tuned a feature called quinoid character, which controls how bond lengths alternate along the chain, by varying one building block's length. Stronger quinoid character evened out the bonds and let charge flow more freely along each chain. Test transistors carried both charge types at high speeds despite modest crystal order. The authors propose bond pattern tuning as a fresh design lever for organic electronics.
