Besides a traditional use for the development of organic conducting materials, the tetrathiafulvalene (TTF) unit and its derivatives have recently appeared as key constituents for new applications, exploiting remarkable redox properties: a high pi-donating ability and occurrence of three stable redox states. Indeed, in very recent years, an impressive variety of switchable TTF-based molecular and supramolecular (multifunctional) architectures have been designed and synthesized. In this feature article, we discuss recent developments of TTF-based molecular and supramolecular systems in this respect, including molecular sensors, redox-fluorescent switches, multi-input systems for logic gates, electrochemically-driven conformational controls, molecular clips and tweezers, and redox-controlled gelation processes.
除了在有机导电材料开发方面的传统用途外，四硫富瓦烯（TTF）单元及其衍生物最近已成为新应用的关键成分，利用了其显著的氧化还原特性：高π供电子能力和三种稳定氧化还原态的存在。事实上，近年来，已经设计并合成了令人印象深刻的各种基于TTF的可切换分子和超分子（多功能）结构。在这篇专题文章中，我们讨论了基于TTF的分子和超分子系统在这方面的最新进展，包括分子传感器、氧化还原荧光开关、逻辑门的多输入系统、电化学驱动的构象控制、分子夹和镊子以及氧化还原控制的凝胶化过程。
