Claim Text:
1. A method of patterning an organic device using a photopolymer, comprising: forming a photopolymer layer on an organic device substrate, the photopolymer layer including a photopolymer comprising at least a first repeating unit having an acid-catalyzed, solubility-altering reactive group, wherein the total fluorine content of the photopolymer is less than 30% by weight; exposing the photopolymer layer to patterned radiation to form an exposed photopolymer layer; and contacting the exposed photopolymer layer with a developing agent to remove unexposed photopolymer, thereby forming a developed structure having a first pattern of exposed photopolymer covering the substrate and a complementary second pattern of uncovered substrate corresponding to the unexposed photopolymer, the developing agent comprising at least 50% by volume of a hydrofluoroether developing solvent.
