Orthogonal Patterning of PEDOT:PSS for Organic Electronics using Hydrofluoroether Solvents



By employing benign process solvents and specially tailored photopolymers, organic electronic materials can be lithographically patterned. Furthermore, because the process is acid stable, this is an ideal candidate for patterning acidic PEDOT:PSS, an important material for organic electronics. Fabrication of a multilayer OTFT demonstrates the potential of this orthogonal patterning process.
