ABSTRACT:
Photoacid generator salts comprising photoactive cationic moieties and segmented, highly fluorinated-hydrocarbon anionic moieties are disclosed which provide high photoacid strength and can be tailored for solubility and polarity. The present invention further relates to photoacid generators as they are used in photoinitiated acid-catalyzed processes for uses such as photoresists for microlithography and photopolymerization.
