Three-dimensional photochemical microfabrication of poly(3,4-ethylene-dioxythiophene) in transparent polymer sheet
A dimeric compound of 3,4-ethylenedioxythiophene was polymerized to form poly(3,4-ethylenedioxythiophene) by multi-photon sensitized polymerization using a femtosecond laser. In contrast, photopolymerization could not be achieved using 3,4-ethylenedioxythiophene as the starting material, because it has a more positive oxidation peak potential compared to the redox potential of the tris(2,2'-bipyridyl) ruthenium complex used as the photosensitizer. Furthermore, three-dimensional micropatterns of poly(3,4-ethylenedioxythiophene) could be produced in a transparent polymer sheet by scanning the laser focal point. (C) 2013 Elsevier B.V.
