    摘要： Polymeric compositions are provided comprising a first plurality of first monomeric units comprising an aromatic group with at least one substituent selected from alkyl, heteroalkyl, alkenyl, heteroalkenyl, alkynyl, heteroalkynyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, and amino, and a second plurality of second multi-functional monomeric units, wherein each multi-functional monomeric unit is capable of forming a branching point in the polymeric composition, thereby resulting in a branched material. Invention compositions therefore have an altered morphology relative to similar non-branched materials. When used to form an EL layer within an EL device, this altered morphology results in EL layers with improved efficiency, which in turn results in more efficient EL devices.

    摘要翻译： 提供聚合物组合物，其包含第一多个第一单体单元，其包含芳族基团和至少一个选自烷基，杂烷基，烯基，杂烯基，炔基，杂炔基，芳基，芳基烷基，杂芳基，杂芳基烷基和氨基的取代基，第二多个 的第二多官能单体单元，其中每个多官能单体单元能够在聚合物组合物中形成支化点，从而得到支链材料。 因此，本发明组合物相对于相似的非支化材料具有改变的形态。 当用于在EL器件中形成EL层时，这种改变的形态导致EL层具有改进的效率，这又导致更有效的EL器件。
