Abstract

Incorporating a steric barrier between the two stations in a bistable [2]rotaxane based on monopyrrolotetrathiafulvalene and cyclobis(paraquat--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) and to follow its interconversion back to the ground-state co-conformation.

摘要

在基于单吡咯并四硫富瓦烯和环双（对苯二酚 - 对苯撑）的双稳态[2]轮烷中，在两个站点之间引入空间位阻，使得在单个氧化还原循环后，高能亚稳态共构象能够被物理隔离，从而使得存储能量（4.4焦耳/升）并跟踪其向基态共构象的相互转化成为可能。
