我们报道了一种具有热激活延迟荧光的高效发光分子，其长延迟荧光寿命为 0.8 ms。尽管反向系间窜越率常数很小，为 2.1 x 10(3) s(-1)，但该分子显示出 89 +/- 2% 的高光致发光量子产率，表明对三重态非辐射衰变的抑制。
We report an efficient luminescent molecule exhibiting thermally activated delayed fluorescence with a long-delayed fluorescence lifetime of 0.8 ms. Although the reverse intersystem crossing rate constant is small at 2.1 x 10(3) s(-1), the molecule shows a high photoluminescence quantum yield of 89 +/- 2%, indicating the suppression of nonradiative decay from the triplet state.
