武汉理工大学夏建龙教授课题组设计合成了一系列以三联苯为桥连单元的并五苯四聚体分子(TPTP-1、TPTP-2、TPTP-3)用于分子内SF研究;发现膜相中分子内SF生成的自由三线态的寿命达到微秒级;并首次提出了利用“分子工程”策略来调控膜相中分子内单线态裂分,实现聚集态下快速的单线态裂分、高产率且长寿命的自由三线态。超快光谱实验结果表明,TPTP分子稀溶液在光照激发下产生的单线态,快速形成三线态激子对,三线态的生成通过三线态敏化实验进一步确认—这与之前文献中报导的并五苯二聚体分子的激发态动力学过程相似,说明溶液中TPTP分子发生了高效的分子内单线态裂分(三线态产率高达180-199%),并且主要是由沿三联苯短轴方向的两个并五苯参与完成。此外,瞬态实验结果还表明在膜相中分子间与分子内的单线态裂分过程同时存在,与二聚体mBP1相比,TPTP分子的单线态裂分生成了更多的自由三线态(40-75%),且三线态寿命增长了103数量级达到了微秒级。该成果以“Achieving Long-lived Triplet States in Intramolecular SF Films Through Molecular Engineering”为题发表在Chem上,武汉理工大学博士生黄华熙和何桂营博士为该论文的共同第一作者。
