Opto-electronic devices fabricated with dual purpose electroactive copolymers

A process for preparing a dual purpose electroactive copolymer comprised of charge transport polymeric segments and a light emitting polymeric segment, which comprises:

• (a) contacting a dihalo-substituted polycyclic aromatic reactant with a living free radical polymerization initiator under conditions effective to bring about polymerization, resulting in a light emitting polymeric intermediate comprised of linked polycyclic aromatic monomer units and two or more displaceable termini;
• and
• (b) synthesizing a charge transport polymeric segment comprised of polymerized charge transporting monomer units at each of the displaceable termini, via living free radical polymerization.

A process for preparing a dual purpose electroactive copolymer comprised of charge transport polymeric segments and a light emitting polymeric segment, which comprises:

• (a) contacting a unimolecular living free radical polymerization initiator with a polymerizable reactant under polymerization conditions, wherein the initiator, the reactant, and the polymerization conditions are effective to provide a charge transporting polymeric intermediate comprised of a plurality of linked monomer units and a single reactive terminus;
• and
• (b) catalytically polymerizing a dihalo-substituted polycyclic aromatic reactant in the presence of the charge transporting polymeric intermediate, whereby a light emitting polymeric segment comprised of linked polycyclic aromatic monomer units is formed, with two or more charge transporting polymeric segments bound thereto.
