课题组在有机室温磷光材料理论设计方面取得重要进展

由于纯有机分子的旋轨耦合比较弱,长期以来有机材料室温下没有磷光。最近,一系列实验发现在固相下纯有机化合物也会表现出高效室温磷光,但其发光效率和寿命不可兼得。在帅志刚和彭谦的指导下,博士后马会利等人提出了一对分子描述符来分别表征磷光效率和寿命。由羰基和π-共轭片段组成的典型RTP体系,其激发态可以视为n→π*跃迁和π→π*跃迁两组分的组合。他们基于光物理原理,特别是El-Sayed规则,引入了一对分子描述符 (γ, β), 其数值的大小与固相下单/三线激发态的(n, π*)和(π, π*)跃迁成分有关。结合量子力学/分子力学(QM/MM)方法,他们揭示了分子描述符 (γ, β) 与磷光效率和寿命以及旋轨耦合之间的关系。他们提出,大的γ和β值有利于有机材料中强的、长寿命的RTP。该研究以题为“Efficient and Long-lived Room Temperature Organic Phosphorescence: Theoretical Descriptors for Molecular Designs”发表于Journal of the American Chemical Society,2019,141,1010-1015。
