具有光学性质的机械柔性有机晶体，由于其奇异的光学现象和广阔的应用前景，引起了人们越来越多的研究兴趣。然而，在有机晶体中实现塑性和发光性质是困难的。本文报道了一种塑性有机晶体氟芬那酸（FFA）III型晶体，它在外力作用下表现出沿（001）面沿着的高塑性弯曲和手扭行为。它还表现出一种独特的弯曲机械荧光行为。总之，所提出的具有机械诱导荧光调制的软单晶似乎对未来可调谐荧光材料的设计感兴趣。
Mechanical flexible organic crystals with optical properties have attracted increasing research interest, because of their unusual phenomena and broad application prospects. However, achieving both plasticity and luminescent properties in organic crystals is difficult. Here we report a plastic organic crystal, flufenamic acid (FFA) form III crystal, which shows highly plastic bending along (001) face and hand-twistable behavior under applied external force. It also illustrated a unique bending mechanofluorochromism behavior. In summary, the proposed soft single crystal with mechanical induced fluorescence modulation appears to be of interest to the design of future tunable fluorescent materials.
