Abstract

We report the synthesis, crystal structures and redox chemistry of two new TTF derivatives bearing fused triaryl units. Both compounds show significant planarisation within conjugated regions, assisted by close intramolecular S...O contacts. The extended-TTF analogue displays multi-redox activity and can be oxidised, sequentially to the tetracation species.
