Abstract: A New Phthalocyanine derivative,the p-toluenesulfonylphthalocyanine was synthesized from metal-free phthalocyanine.The photolysis properties of the compound exposed with UV light was investigated.It was found that the p-toluenesulfonylphthalocyanine can generate acid after exposure.With good photocatalysis property,this photoacid-generator is applicable to chemically amplified photoresist.

Key words: chemical amplification, photoacid generator, photo-catalysis, phthalocyanine
