A lot of 2- or 2,5-substituted EDOT derivatives can be summarized under the heading "molecular band gap engineering." A wide variety of polymers on EDOT basis with "tuned band gap" and hence modified optical properties have been obtained from tricyclic precursors mentioned earlier (see Eigure 13.24). Copolymerization of EDOT with electron-withdrawing thiophene comonomers was utilized to construct low band gap polymers via electro-oxidation and via Stille coupling (see Figure 13.29).
