摘要

在基于单吡咯四硫杂戊烯和环双（百草枯-对苯二酚）的双稳态[2]轮烷中，在两个位点之间加入一个立体屏障，可使高能量的蜕变态共构象在单次氧化还原循环后被物理隔离，从而有可能储存能量（4.4 J L-1），并跟踪其相互转换回到基态共构象。

Pushing a bistable [2]rotaxane out of equilibrium and isolation of the metastable-state co-conformation.

Incorporating a steric barrier between the two stations in a bistable [2]rotaxane based on monopyrrolotetrathiafulvalene and cyclobis(paraquat-p-phenylene) allows the high-energy metastable-state co-conformation to be physically isolated following a single redox cycle, thus making it possible to store energy (4.4 J L^-1) and to follow its interconversion back to the ground-state co-conformation.
