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→(M1)m(M2)n
wherein 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.
本文披露了具有强发光特性和平衡的电荷传输/注入特性的共轭聚合物和共聚物。本文还披露了制造这些聚合物和共聚物以及使用这些聚合物和共聚物制造的光电器件的方法。根据以下聚合反应制备了一种具有可调节电荷传输的共轭发光聚合物:mM1+nM2→(M1)m(M2)n,其中M1是至少具有两个反应性官能团和至少一个具有电子吸引性的化学键结合电荷传输色团的单体,M2是至少具有两个反应性官能团和至少一个具有电子给体性的化学键结合电荷传输色团的单体,其中m和n分别是单体M1和M2的化学计量量,m和n变化以调节共轭发光聚合物的电荷传输性质。单体可以包括芳基,取代芳基和/或多个碳双键,以便在聚合时形成具有共轭骨架的聚合物。聚合反应中可以使用其他单体反应物(M3、M4、M5等)。化学计量单体量的变化可以调节所得共轭发光聚合物的电荷传输或其他电子特性。
