蒽衍生物 9,10-二氰基蒽，结晶为荧光针状单晶，可以很容易地在两个方向上塑性弯曲。空间分辨光致发光分析表明，这种材料具有强大的光电特性，并且在极端晶体变形时仍能保持这种特性。高度灵活的晶体已成功测试为有效的可切换光波导元件，用于主动和被动光转换，并且操作模式取决于入射光的波长。这种原型双模有机光学晶体光纤使机械顺应性分子有机晶体更接近于作为新型光传输介质在全有机微光电器件中无线传输信息的应用。
An anthracene derivative, 9,10-dicyanoanthracene, crystallizes as fluorescent needle-like single crystals that can be readily plastically bent in two directions. Spatially resolved photoluminescence analysis revealed that this material has robust optoelectronic properties that are preserved upon extreme crystal deformation. The highly flexible crystals were successfully tested as efficient switchable optical waveguiding elements for both active and passive light transduction, and the mode of operation depends on the wavelength of the incident light. This prototypical dual-mode organic optical crystalline fiber brings mechanically compliant molecular organic crystals closer to applications as novel light-transducing media for wireless transfer of information in all-organic micro-optoelectronic devices.
