Abstract:
1. A photoacid generator compound of formula (I) wherein each R 1 is chosen from (C 1 -C 10 )alkyl, heteroatom-containing (C 1 -C 10 )alkyl, fluoro(C 1 -C 10 )alkyl, heteroatom-containing fluoro (C 1 -C 10 )alkyl, (C 6 -C 10 )aryl, and fluoro(C 6 -C 10 )aryl; each R 2 is a chemical bond or a (C 1 -C 30 )hydrocarbyl group; each R 3 is H or a (C 1 -C 30 )hydrocarbyl group; R 5 , R 6 and R 7 independently are chosen from an optionally substituted carbocylic aryl group, an allyl group, and an optionally substituted (C 1 -C 20 )alkyl group; X is a chemical bond or a divalent linking group; Z is chosen from an acetoacetoxy ester, —C(O)—O—C(O)—R 1 —, —C(CF 3 ) 2 —, —COO—R f —, —SO 3 —R f —, —OCH 3-z (CH 2 OC(═O)—R f —) z , and a (C 5 -C 30 )cyclohydrocarbyl group comprising a base-reactive group chosen from fluoroalkyl esters, fluorosulfonate esters, and —C(CF 3 ) 2 O—; each R f is independently a fluoro(C 1 -C 10 )alkyl; p=0-6; w=1-3; x=1-4; y=0-5; z=1-2; r=0-1; M is S or I; wherein when M=I, r=0, and when M=S, r=1.
