  从隧道到跳跃介导的从量子点到分子的三重态能量转移的演变

  摘要：

  有效的能量转移对于单线态裂变和光子上转换等多激子过程尤为重要。这里报道了在三重态激子从 CdSe 纳米晶体转移到蒽期间从短程隧穿到长程跳跃的转变。这得到了稳态光子上转换测量、三重态能量转移 (TET) 效率的直接代表以及瞬态吸收测量的坚定支持。当亚苯基桥最初插入在 CdSe 纳米晶体供体和蒽受体之间时，TET 的速率呈指数下降，与光子上转换量子效率从 11.6% 下降到 4.51% 到 0.284% 相称，正如隧道机制所预期的那样。然而，随着刚性桥长度增加到 4 和 5 个亚苯基单元，光子上转换 QY 再次增加到 0.468% 和 0.413%，比使用 3 个亚苯基单元时高 1.5-1.6 倍（使用最大上转换量子效率为 100% 的惯例）。这表明从激子隧穿到跳跃的转变，导致超出传统 1 nm Dexter 距离的相对高效且与距离无关的 TET。瞬态吸收光谱用于确认从 CdSe 到发射器的三
