POLYMER AND ORGANIC LIGHT-EMITTING DEVICE

摘要

Light-emitting composition and devices including the same, the composition including a fluorescent light-emitting material and a polymer having a conjugating repeat unit and a non-conjugating repeat unit in a backbone of the polymer, and in which the conjugating repeat unit provides at least one conjugation path between repeat units linked to it; the non-conjugating repeat unit reduces conjugation of the polymer as compared to a polymer in which the non-conjugating repeat unit is absent; and a triplet excited state energy level of the light-emitting material is higher than a triplet excited state energy level of the non-conjugating repeat unit.
