Abstract
An electrically conductive polymer is comprised of the reaction product of a dendrimer and an electrophoric compound which exhibits .pi.-stacking upon reduction. The reaction product which is a peripherally modified dendrimer is formed and reduced, either chemically or electrochemically, in a polar solvent. The reduced electrophoric moieties aggregate (form .pi.-stacks) to form electrically conductive pathways. The reduced peripherally modified dendrimers of the invention can be cast into films and other solid forms to provide flexible electrical conductors and semiconductors. The conductive polymers of the invention exhibit electrical conductivities comparable to that of doped polyacetalene, but are oxygen and moisture stable.
