| Conducting polymer films are attractive substrates for the construction of flexible electronic and optical devices. Poly(3,4-ethylenedioxythiophene), PEDOT, may be formed as exceptionally smooth, nearly optically transparent films after a sublimation/polymerization process from 2,5-dibromo-3,4-ethylenedioxy)thiophene, followed by thermal annealing. Thiols react with the polycationic backbone, and can act as anchors to attach functional molecular systems to the surface. Here, we report the attachment of porphryins to these surfaces. The porphyrin-linked thiols assemble on the polymer surface with some degree of organization and, when appropriately functionalized, can undergo systematic cross-coupling reactions with additional porphyrins to create designer arrays. |
