  邻氟偶氮苯作为易于合成的光开关，可在可见光下提供近乎定量的双向异构化

  摘要：

  用邻氟原子官能化的偶氮苯具有较低的 Z 异构体 n 轨道能量，导致 E 和 Z 异构体的 n→π* 吸收带分离。引入对位取代基可以进一步调整邻氟偶氮苯的吸收光谱。特别是，吸电子酯基会导致 n→π* 跃迁的间隔为 50 nm。因此，绿光和蓝光可分别用于诱导 E→Z 和 Z→E 异构化。邻氟偶氮苯支架很容易合成，并且可以通过其芳基末端插入更大的结构中。这些新的偶氮苯衍生物可以通过两种方式进行转换，具有高光转化率，并且它们的 Z 异构体显示出非常长的热半衰期。

  A new strategy for controlling the liquid crystalline and photophysical properties of supramolecular mesogens assembled via halogen bonding is reported. Changing the degree of fluorination at the halogen-bond donor of the supramolecular liquid crystal allows for the fine-tuning of the halogen bond strength and thereby provides control over the temperature range of the mesophase. At least three fluorine
