The Preparation of rather complex molecular assemblies can now be accomplished by using a complete set of tetrathiafulvalene (TTF) based building blocks. The facile deprotection of the 2-cyanoethyl group, a versatile protecting group for 1,3-dithiolium-2-thione-4,5-dithiolaes and TTF-thiolates have proven to be a viable method for the incorporation of TTF units into macrocyclic and supramolecular compounds. Especially the stepwise protection-deprotection methodology have been used extensively by our group for the preparation of two and three dimensional macrocyclic (mono-, bis- and tricyclic) as well as TTF-based supramolecular systems. The generation, utilization and scope of the generated thiolates are illustrated by several examples: Dendrimeric and oligo-TTF's, three dimensional tetrathafulvalenophanes, TTF-containing catenanes and rotaxanes and donor acceptor systems based on TTF as the donating portion.
现在,通过使用一整套基于四

硫环戊烯和
TTF-
硫代酸酯的通用保护基团,对该基团进行简易脱保护已被证明是将
TTF 单元加入大环和超分子化合物的可行方法。特别是分步保护-保护方法已被我们小组广泛用于制备二维和三维大环(单环、双环和
三环)以及基于
