Abstract
The room-temperature phosphorescence (RTP) of metal-free organic crystals is normally quenched by mechanical stimulation. Herein, we demonstrate the opposite mechanoresponse of turn-on RTP. A desymmetrization of a C-symmetric 1,2-diketone creates space for molecular motion in the crystal, quenching the RTP from the crystal while maintaining that from the amorphous solid.
摘要
室温磷光（RTP）的金属有机晶体通常会被机械刺激猝灭。在此，我们展示了相反的机械响应开RTP。一个 C 对称的 1,2-二酮的非对称化在晶体中为分子运动创造了空间，从而猝灭了晶体中的 RTP，同时保持了非晶态固体中的 RTP。
