Abstract
The idea that conjugated polymers with alternate donor and acceptor mo ieties in the main chain are characterized by a small band gap is prop osed and explained. Experimental verification of this idea is reported in new classes of conjugated polymer semiconductors, polysquaraines a nd polycroconaines. These new materials show band gaps down to 0.5 eV, conductivities around 10(-5) S/cm and are stable in air up 250-degree s-C or higher.
