relationship within a series of sulfonium salts synthesized using a cyclization strategy. The new sulfonium salt comprises a stilbene subunit decorated with a combination of cyclized structure, that is, carbocyclic ring, furan ring, and thiophene ring, to inhibit the isomerization of double bond systems. The photoacid generation efficiency of such cyclized stilbene derivative sulfonium salts is mainly modulated
