A Flavin-based [2]catenane

摘要

Controlled molecular motion processes are ubiquitous in nature and have inspired chemists to create synthetic analogues in the form of molecular machines. By virtue of their topology, molecular machines fabricated from catenanes (mechanically interlocked macrocycles) can undergo controlled rotational motion under the influence of an external stimulus (e.g. electrochemistry). As a consequence catenane-like architectures are attractive systems for the development of biomimetic and synthetic rotary motors and components for molecular electronics.rnMolecular machines fabricated from hydrogen bonded interlocked structures have emerged as important systems for the development of chemically, photochemically and electro-chemically controllable assemblies. Although a range of moieties have been incorporated into these architectures to facilitate controlled molecular motion, there still remains scope for the development of systems containing new molecular components.
