荧光特性不仅可以用于跟踪微环境中的单个分子,而且可以用于分子尺度的光电子学。在这里,我们使用外部光刺激来打开和关闭嵌入在聚合物薄膜中的单个光致变色分子的荧光。这种数字响应是由于分子的光异构化,这可能最终在可擦除的光学数据存储元件中找到应用。
Fluorescent properties can be useful not only for tracking individual molecules within a microenvironment, but also in molecular-scale opto-electronics. Here we use external photostimulation to switch the fluorescence on and off from a single photochromic molecule embedded in a polymer film. This digital response is due to photo-isomerization of the molecule, which may eventually find application in erasable optical data-storage elements.
