  仿生分子开关的光化学表征

  摘要：

  研究了芴基吡咯啉（FPs）和N-烷基化芴基吡咯啉（NAFPs）衍生物用作光驱动分子开关的性能。两种类型的化合物均具有快速且可控的光异构化作用。已经考虑了可能导致效率低下的其他竞争性反应途径。长时间照射这些化合物时，只能测到微弱的荧光，并且发现高的光稳定性，以及高的光异构化量子产率。NAFP能够使用可见光，这对于实际应用可能是有用的。

  Fluorenylidene−Pyrroline Biomimetic Light-Driven Molecular Switches

  摘要：

  A new family of biomimetic photoactivated molecular switches based in the retinal chromophore is described. Expedient synthesis allows a library of compounds with a different substitution pattern, including chiral substituents, to be obtained. The effect of substitution, solvent, and light source on the photoisomerization step has been assessed. The absorption maximum has been red-shifted ca. 50 nm with respect to related systems and rotation is now easily achieved by using visible light.

  been studied. Both types of compounds share fast and controllable photoisomerization. Other competitive reaction pathways that could lead to low efficiency have been considered. Only weak fluorescence was measured and high photostability was found when irradiating these compounds for long times, together with high photoisomerization quantum yields. NAFPs are capable of using visible light, which could
