  摘要：

  通过在有机胶体介质中使用二芳基乙烯光致变色化合物，实现了苝染料在开关状态之间的荧光发射调制，效率极高。荧光胶体是由掺杂苝荧光分子的类固醇低分子量有机胶体形成的。证明了光致变色化合物在该介质中的兼容性和非破坏性读取能力。掺染染料的有机胶体进一步作为模板，采用创新方法生长了物理和化学混合的荧光二氧化硅球形纳米颗粒。

  单晶相中 1,2-双（2-甲基-6-硝基-1-苯并噻吩-3-基）全氟环戊烯的光致变色：闭环形式异构体的二色性

  摘要：

  发现 1,2-双 (2-甲基-6-硝基-1-苯并噻吩-3-基) 全氟环戊烯在单晶相中发生可逆的光致变色反应。在用 366 nm 光照射后，单晶在保持晶体形状的情况下变成绿色。有色晶体显示二色性。当晶体在偏振光下旋转时，颜色由黄色变为蓝色。黄色和蓝色归因于闭环形式在 465 和 600 nm 处的两个垂直电子跃迁。两个过渡矩与闭环形式异构体的短轴和长轴方向一致，它们规则地堆积在晶格中。

  A photochromic diarylethene crystal of 1,2‐bis(2‐methyl‐6‐nitro‐1‐benzothiophen‐3‐yl)perfluorocyclopentene (1 a) was found to undergo a thermodynamic phase transition at 180 °C to form a needle‐like crystal, designated as 1 a‐γ. The phase transition involves melting of the initial α‐crystal and growth of the γ‐crystal. The phase transition temperature decreased with the presence of the closed‐ring

  1,2-双（2-甲基-6-硝基-1-硝基苯并噻吩-3-基）全氟环戊烯（1 a）的光致变色二芳基乙烯晶体在180°C时发生热力学相变，形成针状晶体，命名为1a-γ。相变涉及初始α晶体的熔化和γ晶体的生长。由于熔融温度降低，晶体中存在闭环异构体（1 b）时，相变温度降低。紫外线（UV）照射后，α-晶体中的化合物1a转化为1b的程度达到20％。因此，含有20％1b的α晶体甚至在170°C时也经历了相变，伴随着晶体的熔化和γ晶体的生长。通过使用光掩模在UV光照射下进行相变并随后在170℃下加热而成功地以约20μm的微晶图案的分辨率完成了通过相变进行的光微图案化。玻璃基板上的γ微晶相与水的接触角比α微晶相与水的接触角大20°。这可以归因于表面粗糙度的差异。此外，还发现加热1 a的非晶膜会形成γ微晶。在130°C下在聚（甲基丙烯酸甲酯）中溶解2分钟。结晶区域显示出比非晶区域更高的水接触角。当用UV光非

  A toy comprises a toy element comprising a photochromic layer which contains a photochromic compound having a photo memory function (color-memorizing photochromic property), maintains a coloring state by developing a color through the irradiation of ultraviolet rays or sunlight containing ultraviolet rays and changes into decolorizing state through its decolorization by the irradiation of visible light, and a color-changing means which contains at least one of an ultraviolet ray absorbent and a light-shading pigment capable of shading at least ultraviolet rays, changes the photochromic compound of the coloring state into decolorizing state by cutting off ultraviolet rays of sunlight and thereby effecting irradiation of visible light, and maintains the changed state, wherein a function to memorize and maintain coloring and decolorizing states alternately is expressed by arranging the color-changing means under such a condition that it is covering or not covering the photochromic layer.
