Room-temperature phosphorescence (RTP) with p-π and π-π synergy is realized by combining phosphine and carbazole groups in three hybrid molecules (xCzTPP). The harmonized p-electronic feature and steric effect of the phosphine group result in RTP efficiency and lifetime of para-substituted pCzTPP up to 13.8 % and 645 ms, respectively, owing to its sequential and complementary triplet p-π and π-π components in intersystem crossing and triplet energy-transfer processes.

磷化氢调控的 p-π 和 π-π 协同作用可实现高效的超长有机室温磷光

通过在三个杂化分子 ( x CzTPP)中结合膦和咔唑基团，实现了具有p -π 和 π-π 协同作用的室温磷光 (RTP )。膦基团的协调p电子特征和空间效应导致对位取代的p CzTPP 的 RTP 效率和寿命分别高达 13.8% 和 645 ms，这是由于其连续和互补的三重态p -π 和 π-π 分量在系间交叉和三线态能量转移过程中。
