Pressure not only influences the yield in the synthesis of a two-station [2]rotaxane, it also determines the distribution of the co-conformational isomers. At high pressure cyclobis(paraquat-p-phenylene) is preferentially assembled around a monopyrrolotetrathiafulvalene unit, while at low pressure it is preferentially assembled around a hydroquinone unit.
压力不仅影响[2]轮烷合成的产率,还决定了共构异构体的分布。在高压下,环双(对醌-对亚苯基)优先围绕一个单吡咯并四噻吩单元组装,而在低压下,它优先围绕一个对苯二酚单元组装。
