Conjugated polymers with tunable charge injection ability
Conjugated polymers and copolymers with strong luminescent properties and balanced charge transporting/injection properties are disclosed. Methods of manufacturing such polymers and copolymers and optoelectronic devices fabricated with such polymers and copolymers are disclosed. A conjugated luminescent polymer with tunable charge transport is prepared according to the following polymerization reaction:mM1+nM2&#8594;(M1)m(M2)nwherein M1 is a monomer having at least two reactive functional groups and at least one chemically bonded charge transporting chromophore group possessing electron-withdrawing character and M2 is a monomer having at least two reactive functional groups and at least one chemically bonded charge transporting chromophore group possessing electron-donating character, wherein m and n are stoichiometric quantities of the monomers M1 and M2, respectively, wherein m and n are varied to tune the charge transport property of the conjugated luminescent polymer. The monomers may include aryl, substituted aryl, and/or multiple carbon double bonds so that when polymerized, the resulting polymer has a conjugated backbone. Additional monomer reactants (M3, M4, M5, etc.) can be used in the polymerization reaction. The stoichiometric monomer amounts are varied to tune the charge transport or other electronic properties of the resulting conjugated luminescent polymer.
