Abstract: An organic electronic or an optoelectronic device containing a conjugated oligoelectrolyte. In more particularized embodiments, the conjugated oligoelectrolyte is the charge injection or transport layer. The conjugated oligoelectrolyte can be positively or negatively charged, and used in conjunction in a device with either or high or low work function metal.

Abstract: A salt is provided comprised of a polyionic conjugated polymer comprising a plurality of first charges; and a plurality of counterions, each of said plurality comprising a charged moiety electronically linked to at least one charge-distributing moiety, said charged moiety having a charge opposite in sign to that of the first charge. These polyionic conjugated polymers having different electronic and/or optical properties.
