research of crystal engineering. Although a few EOSCs have been reported recently, those suitable for optical/optoelectronic applications have not been realized. Here, we report an elastic crystal of a Schiff base, (E)‐1‐(4‐(dimethylamino)phenyl)iminomethyl‐2‐hydroxyl‐naphthalene. The crystal is highly bendable under external stress and able to regain immediately its original straight shape when the stress
弹性有机单晶(E

萘的弹性晶体。晶体在外部应力下具有高度的弯曲性,并且在应力释放后能够立即恢复其原始的笔直形状。它显示出明亮的橙红色发射,具有0.43的高荧光量子产率。有趣的是,即使在高度弯曲的状态下,它也可以用作低损耗的光波导。我们的结果突出了有机晶体“弹性”的特征和效用。
