Disclosed are a polymer, and a mixture or a formulation and an organic electronic device containing same, and applications thereof, and further a monomer of which the polymer is made; the polymer comprises on its side chain a repeating structure unit E, characterizing in that its S1(E)−T1(E))≤0.35 eV or even less, which may allow the said polymer having thermally activated delayed fluorescence (TADF) property. Thus a TADF polymer suitable for printing processes is provided, thereby reducing OLED manufacturing costs.
公开了一种聚合物,以及包含该聚合物的混合物或配方和有机电子器件,以及其应用,以及该聚合物所制成的单体;该聚合物在其侧链上包含重复结构单元E,其特征在于其S1(E)−T1(E))≤0.35 eV甚至更低,这可能使得该聚合物具有热激活延迟荧光(TADF)特性。因此,提供了一种适用于印刷工艺的TADF聚合物,从而降低OLED制造成本。
