We developed new photoresponsive polydiacetylene (PR-PDA) molecules by incorporating a photocleavable moiety, 6-nitropiperonyl alcohol (NP) or 4,5-dimethoxy-2-nitrobenzyl alcohol (DMN), into a self-assembling diacetylene molecule. Inducing steric disordering of the assembled PDA molecules by the cleavage of the photoresponsive moiety under 365 nm UV irradiation results in color transition from blue to red and development of red fluorescence, allowing convenient photo patterning. Further writing and erasing of fluorescence patterns are demonstrated toward novel secure information communication and anticounterfeiting applications.

新型光响应性聚二乙炔分子的快速光驱动颜色转变

我们通过将可光裂解的部分，6-硝基胡椒基醇（NP）或4,5-二甲氧基-2-硝基苄基醇（DMN）结合到自组装的二乙炔分子中，开发了新的光敏聚二乙炔（PR-PDA）分子。在365 nm紫外线照射下，光敏部分的裂解引起组装的PDA分子的空间混乱，导致颜色从蓝色过渡到红色，并形成红色荧光，从而可以方便地进行照片构图。朝着新颖的安全信息通信和防伪应用展示了荧光图案的进一步写入和擦除。
