Triphenylsulfonium salt compound, and uses thereof

A triphenylsulfonium salt compound, having a structure represented by the following general formula (II) or general formula (III) or general formula (IV):

• wherein,
• R1 represents an electron-withdrawing group, selected from the group consisting of halogen, cyano, nitro, alkoxy, haloalkyl, acyl, acyloxy, and sulfonyl;
• R2 represents an amplification group, selected from the group consisting of halogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, and substituted or unsubstituted aralkyl;
• each R3 independently represents any of halogen, nitro, cyano, hydroxy, acyl, acyloxy, sulfonyl, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, and substituted or unsubstituted aralkyl;
• the carbon-carbon bond in the groups representing R3 in the general formula (II) may be interrupted by —O— or —S—, and R3 groups may be connected with each other to form a ring;
• each R4 and R5 independently represent any of halogen, nitro, cyano, hydroxy, acyl, acyloxy, sulfonyl, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, and substituted or unsubstituted aralkyl;
• optionally, —CH2— in the groups representing R4 in the general formula (IV) may be replaced with —O—, —S—, or —CH═CH—, the carbon-carbon bond in the groups representing R4 and R5 in the general formula (II) may be interrupted by —O— or —S—, and R4 groups may be connected with each other to form a ring, and R5 groups may be connected with each other to form a ring;
• in the general formula (IV), m represents 0, 1, or 2;
• wherein when m is 1, R4 in the general formula (IV) is located at the para-position of S in the benzene ring group, and when m is 2, adjacent R4s together with phenyl connected with R4 form a ring;
• in the general formula (II), n represents any integer of 0 to 5, and m and p each independently represent any integer of 0 to 4;
• and
• in the general formula (III), n and m each independently represent an integer of 1 to 5,
• X− represents a non-nucleophilic anion, and
• in the general formula (II), A and M each independently represent a linking group.
