Abstract
A photosensitive composition comprises a fluorinated solvent, a photo-acid generator and a copolymer. The copolymer comprises at least three distinct repeating units, including a first repeating unit having a fluorine-containing group, a second repeating unit having an acid-catalyzed cross-linkable group, and a third repeating unit having a sensitizing dye. The composition is useful in the fabrication of electronic devices, especially organic electronic and bioelectronic devices.
