POLYMER, MIXTURE AND COMPOUND CONTAINING SAME, AND ORGANIC ELECTRONIC DEVICE AND MONOMER THEREOF

摘要

Disclosed are a polymer, a compound containing same, and an organic electronic device and application thereof; the polymer comprises on its side chain a repeating structure unit E, which has thermally activated delayed fluorescence (TADF), i.e. Δ(S1(E)-T1(E))≤0.35eV. Thus a TADF polymer suitable for printing processes is provided, thereby reducing OLED manufacturing costs.
