説明

<jats:title>Abstract</jats:title><jats:p>Bendable (elastic and plastic) organic single crystals have been widely studied as emerging flexible materials with highly ordered packing structures. However, even though manifold bendable organic crystals have been recently reported, most of them bend in response to only one stimulus. Herein, we report an organic single crystal of (<jats:italic>Z</jats:italic>)‐4‐(1‐cyano‐2‐(4‐(dimethylamino)phenyl)vinyl)benzonitrile, which bends under external stress (physical process) and also hydrochloric acid atmosphere (chemical process). This observation indicates that a single organic crystal, whose structure has been optimized simultaneously at both the molecular and supramolecular levels, may display multiple crystal‐bending modes. Furthermore, the crystals exhibit bright orange‐yellow emission and can serve as an active low‐loss optical waveguide in both the straight and the bent state, which indicates a potential optical application.</jats:p>
