Abstract
A fluorinated photopolymer composition is disclosed having a branched copolymer provided in a fluorinated solvent. The copolymer includes a branching unit, a first repeating unit having a fluorine-containing group, and a second repeating unit having a solubility-altering reactive group. The branched fluorinated photopolymer composition is particularly suited for the fabrication of organic electronic and bioelectronic devices, or other devices having sensitive active organic materials.
