Patent abstract
A photosensitive composition is disclosed including a fluorinated photo cross-linkable polymer provided in a fluorinated solvent such as a hydrofluoroether. The photo cross-linkable polymer includes a first repeating unit having a fluorine-containing group but not a cinnamate group, and a second repeating unit having a fluorine-containing cinnamate group. The polymer has a total fluorine content in a range of 30 to 60% by weight. The composition can be used to form patterned barrier or dielectric structures over substrates and devices such as organic electronic devices.
