Abstract
A complete set of tetrathiafulvalene (TTF) based building blocks have been developed, allowing easy construction and preparation of complex molecular assemblies. The facile deprotection of the 2-cyanoethyl group, a versatile protecting group for 1,3-dithiolium-2-thione-4,5-dithiolates as well as TTF-thiolates, is an excellent method for the incorporation of TTF units into macrocyclic and supramolecular compounds. This selective and 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. Recent examples described here are: Dendrimeric and oligo-TTF's, three dimensional tetrathiafulvalenophanes, TTF-containing catenanes and donor acceptor systems based on TTF as the donating group.
