文摘

3,4-Ethylenedioxythiophene (EDOT)-based conjugated polymers bearing tetrahydropyranylside groups were synthesized. These include poly[(3-(2-(2-tetrahydropyranyloxy)ethyl)thiophene)-(3,4-ethylenedioxythiophene)] (PTHPET-EDOT), and poly[(3-(11-(2-tetrahydropyranyloxy)undecyl)thiophene)-(3,4-ethylenedioxythiophene)] (PTHPUDT-EDOT). PTHPUDT-EDOT exhibits an enhanced stability in its oxidized state and a high optical contrastratio between its reduced and oxidized states. Despite its rigid-rod nature, PTHPUDT-EDOT undergoes an acid catalytic reaction that leads to the cleavage and completeelimination of the tetrahydropyranyl group. The decrease in solubility of the deprotectedpolymer allows for the deposition of PTHPUDT-EDOT in a spatially controlled fashion usingchemically amplified photolithography and soft lithography.
