Abstract

Long-lived room temperature ‘phosphorescence’ from organic molecular crystals has attracted great attention owing to potential applications in organic electronics, information storage, and biotechnologies. The features of the persistent luminescence strongly depend on the electronic properties of the individual molecules, and on their molecular packing in the crystal lattice. Here, a new strategy is developed by rationally designing phosphors incorporating and combining for the first time a bridge for sigma-conjugation and a moiety for H-bond-directed supramolecular self-assembly. The molecular crystals exhibit room temperature ‘phosphorescence’ quantum yields that reach up to 20% and lifetimes up to 520 ms. This study provides a promising strategy for the development of molecular crystals exhibiting efficient long-lived room temperature persistent luminescence.

合理设计无金属有机发色团,通过氢键导向的超分子自组装形成高效的室温持续发光分子晶体
由于在有机电子、信息存储和生物技术方面的潜在应用,来自有机分子晶体的长寿命室温“磷光”引起了人们的极大关注。持续发光的特征强烈地依赖于单个分子的电子性质,以及它们在晶格中的分子堆积。本文提出了一种合理设计的新策略,首次将sigma偶联桥和氢键导向的超分子自组装部分结合在一起。分子晶体表现出室温下的“磷光”量子产率高达20%,寿命高达520毫秒。该研究为开发具有高效长寿命室温持续发光的分子晶体提供了一条有前途的策略。
