Abstract:Molecular doping can increase conductivity in organic
semiconductor
solids through the addition of an electron donor or acceptor into
the organic host matrix, when ground state charge transfer interactions
are induced between the matrix and the dopant that facilitate carrier
transport. Aryl-substituted diketopyrrolopyrroles are common motifs
in both small molecules and polymers used for organic electronics,
but their molecular doping has only begun to be explored. In this
work, we describe a ground state charg… Show more
