synthesized a TTF with an oligomethylene arm terminated by a thiol group and assembled monolayers of this compound on gold. We have observed that the cyclic voltammogram of the immobilized TTF donors varies significantly upon addition of benzyl viologen, tetracyanoquinodimethane (TCNQ), or tetracyanoethylene (TCNE) acceptors to the electrolyte solution. Indeed, the supramolecular association of the complementary

The convergent synthesis of a TTFâglycol dendrimer is reported: thin layer cyclic voltammetric studies on (TTF)21 system 11 show that all the TTF units undergo two single-electron oxidations to produce the 42+ redox state spectroelectrochemical studies establish that there are intradendrimer interactions between partially-oxidised TTF units.
Two linear oligo-TTFs were synthesised employing a stepwise
strategy involving two different thiolate protecting groups. These linear
TTFs were incorporated into donor–acceptor rotaxanes with the cyclic
acceptor, cyclobis(paraquat-p-phenylene). Moreover, a prototype rotaxane based on a bis(pyrrolo)-TTF
was prepared and studied.
Treatment of cyanoethylated tetrathiafulvalene-thiolates or cyanoethylated 1,3-dithiole-2-thione-4,5-dithiolate with one equiv. of caesium hydroxide hydrate selectively and in high yield produces the corresponding monocaesium salts, which can subsequently be alkylated.

The synthesis of tetrathiafulvalenophanes 4b, 4c, 5, 9, and 10 employing two fundamentally different strategies is reported. Macrocycle 9 was obtained as a mixture of cis and trans isomers and was crystallized to afford two distinct crystals types: a red type consisting of the cis isomer and a yellow type consisting of the trans isomer. The crystal structures of cis-9 and trans-9, determined by X-ray diffraction, revealed that the cis-form possesses a planar TTF moiety while the trans-form has a distorted TTF unit. The electrochemical properties of the new tetrathiafulvalenophanes are reported.
