  表现热自旋上转换的供体-受体分子的光物理性质和高效，稳定的电化学发光

  摘要：

  由三氰基苯和甲基，叔丁基和苯基取代的咔唑基，1,2,3,5-四（3,6-二取代的-）组成的三个供体-受体分子的光物理性质和电化学发光（ECL）描述了咔唑-9-基）-4,6-二氰基苯（分别为4CzIPN-Me，4CzIPN- t Bu和4CzIPN-Ph）。这些分子由于在室温下从最低的三重态到最低的单重态热自旋上转换而显示出延迟的荧光。这三个分子显示黄色至淡黄色红色ECL。值得注意的是，4CzIPN-的ECL效率吨卜在二氯甲烷几乎达到了40％。此外，稳定的ECL从4CzIPN-发射吨Bu和4CzIPN‐Ph。对于4CzIPN-Me，由于聚合，在电压周期内ECL强度会降低。量子化学计算表明，聚合反应由笨重的空间位阻抑制了叔丁基和苯基的咔唑基结构部分，并通过4CzIPN-PH电子共轭降低在咔唑基的自旋密度。

  2,4,5,6-Tetrakis(3,6-di-tert-butyl-9H-carbazol-9-yl)isophthalonitrile (4CzIPN-tBu) was developed as a photocatalyst for the phosphorus-radical-initiated cascade cyclization reaction of isocyanides. By using 4CzIPN-tBu as catalyst, we developed a visible-light-induced proton-coupled electron transfer strategy for the generation of phosphorus-centered radicals, via which a wide range of phosphorylated

  Emissive layers for electroluminescent display devices are described herein. The emissive layer can include a two-dopant system having a population of quantum dots (QDs) and a population of molecules exhibiting thermally activated delayed fluorescence (TADF). In some instances, one or both of the QDs and TADF molecules can be disposed in a host matrix. In some instances, the QDs and TADF molecules can be disposed in separate host matrices. In some instances, an electroluminescent display device can include an emissive layer comprising a population of quantum dots (QDs) and a layer adjacent to the emissive layer, the adjacent layer comprising a population of molecules exhibiting thermally activated delayed fluorescence (TADF).
