K-Ras is the most frequently mutated oncogene in human cancer. Disclosed herein are compositions and methods for modulating K-Ras and treating cancer.

Non-ionic photo-acid generating (PAG) compounds were prepared that contain an aryl ketone group having a perfluorinated substituent alpha to the ketone carbonyl. The non-polymeric PAGs release a sulfonic acid when exposed to high energy radiation such as deep UV or extreme UV light. The photo-generated sulfonic acid has a low diffusion rate in an exposed resist layer subjected to a post-exposure bake (PEB) at 100 C. to 150 C., resulting in formation of good line patterns after development. At higher temperatures, the PAGs can also undergo a thermal reaction to form a sulfonic acid. The perfluorinated substituent provides improved thermal stability and hydrolytic/nucleophilic stability.

Non-ionic photo-acid generating (PAG) polymerizable monomers were prepared that contain a side chain sulfonate ester of an alpha-hydroxy aryl ketone. The aryl ketone group has a perfluorinated substituent alpha to the ketone carbonyl. The sulfur of the sulfonate ester is also directly linked to a fluorinated group. PAG polymers prepared from the PAG monomers release a strong sulfonic acid when exposed to high energy radiation such as deep UV or extreme UV light. The photo-generated sulfonic acid has a low diffusion rate in an exposed resist layer subjected to a post-exposure bake (PEB) at 100 C. to 150 C., resulting in formation of good line patterns after development.
