A highly constrained [2]rotaxane, constructed in such a way that the tetracationic cyclobis(paraquat-p-phenylene) ring is restricted to reside on a monopyrrolotetrathiafulvalene unit, has been synthesised and characterised. This design allows the deslipping free energy barrier for the tetracationic ring in all three redox states of the rotaxane to be determined.
我们合成了一种高度受限的 [2]rotaxane 并对其进行了表征,这种化合物的构造方式限制了四阳离子环双(百草枯-对苯二甲酸)环驻留在单吡咯四硫杂戊烯单元上。通过这种设计,可以确定四阳离子环在轮烷所有三种氧化还原状态下的脱脂自由能障。
