合成了光开关对映体纯的亚磺酰基偶氮化合物。一个显着的扰动的偶氮系统的立体亚磺酰基部分已被观察到的CD在反式和顺式偶氮苯光异构化产生的。经过五个照射周期后,这些手性开关的构型完整性保持不变。
Photoswitchable enantiopure sulfinyl azo compounds have been synthesized. A remarkable perturbation of the azo system by the stereogenic sulfinyl moiety has been observed by CD in both the trans and the cis azobenzenes resulting by photoisomerization. After five irradiation cycles, the configurational integrity of these chiral switches remains unchanged.
