The transfer of molecular machine technology into aggregated states is a key step for the realization of many potential applications. Here we report three organic luminescent agents, CzS-o-py, CzS-m-py, and CzS-p-py, that can adjust organic room-temperature phosphorescence (RTP) via orderly stimulus-responsive molecular motion in the crystal. Careful analysis of the single-crystal structure before and after ordered molecular motion, coupled with theoretical calculations, reveals the effective intermolecular charge transfer generated by the dense packing mode to be responsible for the RTP effect. Accordingly, a dual anti-counterfeiting application is successfully implemented, exploiting the RTP effect of the stimulus response. The introduction of molecular mechanical technology may provide a strategy for the molecular design, internal mechanism exploration, and practical application of RTP luminescent agents.

将分子机器技术转变为聚集态是实现许多潜在应用的关键步骤。在这里，我们报告三种有机发光试剂，CzS- Ø -py，CzS-米-py和CzS- p -吡咯可以通过晶体中有序的刺激响应分子运动来调节有机室温磷光（RTP）。仔细分析有序分子运动前后的单晶结构，再加上理论计算，揭示了由致密堆积模式产生的有效分子间电荷转移是造成RTP效应的原因。因此，利用刺激响应的RTP效果，成功实现了双重防伪应用。分子机械技术的引入可为RTP发光剂的分子设计，内部机理探索和实际应用提供策略。
