Macrocyclic, Molecular, and Supramolecular TTF Systems

摘要: The sulfur-containing heterocycle, tetrathiafulvalene (TTF) and its derivatives have been intensively studied during the past two decades on account of their unique π electron donor properties. They were originally prepared for development electrically conducting materials have, as such, synonymous with molecular organic metals. However, few years, utility TTF building blocks in macrocyclic supramolecular chemistry has revealed that moiety is useful beyond field chemistry. Progress synthetic enabled preparation elaborate architectures consequently incorporated into a number systems, such cyclophanes, catenanes, rotaxanes, dendrimers, polymers. Molercular devices based host-guest interactions may act example sensors or switches. Among these systems mechanically-interlocked catenanes rotaxanes are now prime candidates construction artificial machines fabrication electronic devices.
