  Novel Photochromic Homopolymers Based on 1,2-Bis(3-thienyl)cyclopentenes

  摘要：

  Incorporation of photochromic molecules into polymer matrices is necessary for materials applications such as optical information processing. Several novel homopolymers were prepared from 1,2-bis(3-thienyl)cyclopentene derivatives using ring-opening metathesis polymerization techniques. Analysis by UV-vis absorption spectroscopy revealed that, in solution, they retained the appealing photochromic behavior exhibited by their respective monomers. The polymers were cast as thin films and spin-coated onto quartz substrates where the solid-state photochromic properties of the polymers were similar to those in solution.

  A new diarylethene derivative containing an aminoquinoline unit was synthesized and its structure was determined by single crystal X‐ray diffraction analysis. Its properties such as photochromism, fluorescent switches and detection for metal ions were measured. The results indicated that the closed‐ring of the diarylethene was highly selective toward Cu2+ with an obvious absorption decrease and color

  合成了一种新的含有氨基喹啉单元的二芳基乙烯衍生物，并通过单晶X射线衍射分析确定了其结构。测量了其特性，例如光致变色，荧光开关和金属离子检测。结果表明，即使在存在其他金属离子的情况下，二芳基乙烯的闭环对Cu 2+的选择性也很高，吸收率明显降低，颜色从蓝色变为无色。该新的二芳基乙烯与Cu 2+的封闭异构体的结合常数为2.0×10 4 L·mol -1，Cu 2+的检出限经计算，其含量低于饮用水中的含量。最后，利用光和Cu 2+的组合刺激的输入，利用吸收强度作为输出信号来构造逻辑电路。
