Synthesis and electropolymerisation of 3,4-alkylenedioxythiophenes

We prepared 2,3,4,5-tetrahydrothieno[3,4-b][1,4]dioxocine- BuDOT and [3,4-b][3',4'-l]-dithieno-1,4,11,14-tetraoxacycloeicosane. We tried to electropolymerise both and found that while BuDOT polymerises easily the second monomer shows difficulty polymerising in organic solvents used. Electrochemical stability of PBuDOT was investigated using cyclic voltammetry and the polymer was found to be stable in the (-0.6 V) 1.55 V potential range.
