Synthesis and electrochemical properties of a silyl-substituted tetrathiafulvalene derivative

► A silyl-substituted TTF and 1,3-dithiole-2-(thi)one were synthesized. ► Their structures were confirmed by NMR, MS and IR. ► Cyclic voltammetry of the new TTF derivative was determined. ► The formation of CT complex between the donor and DDQ was demonstrated.
