We describe a [2]rotaxane whose recognition sites for the ring are a dibenzylammonium moiety, endowed with acidic and H-bonding donor properties, and an imidazolium center bearing a photoactive phenylazo substituent. Light irradiation of this compound triggers a network of / isomerization and proton transfer reactions that enable autonomous and reversible ring shuttling away from equilibrium.
我们描述了一种[2]轮烷,其环的识别部位为具有酸性和氢键供体性质的二苄基铵部分和带有光活性苯偶氮取代基的咪唑鎓中心。该化合物的光照射引发了一系列的异构化和质子转移反应,使轮烷能够自动和可逆地远离平衡进行环穿梭。
