Pag triphenylsulfonium
WebWe describe new sulfonium salts incorporating semifluorinated sulfonate anions and their successful application as photoacid generators (PAGs) intended to solve the environmental problems caused by perfluorooctyl sulfonate (PFOS). By utilizing simple and unique chemistries based on 5-iodooctafluoro-3-oxapentanesulfonyl fluoride, a series of alicyclic … WebSpecifically, the following PAGs were separately incorporated into the main-chain of the polymers: the isomers triphenylsulfonium salt 2-(methacryloxy)-4-trifluoromethyl benzenesulfonate and triphenylsulfonium salt 4-(methacryloxy)-2-trifluoromethyl benzenesulfonate (CF3 PAG); triphenylsulfonium salt 4-(methacryloxy)-3-nitro …

PAGs undergo proton photodissociation irreversibly, while PAHs are molecules that undergo proton photodissociation and thermal reassociation. In this latter case, the excited state is strongly acidic, but reversible. Photoacid generators. An example due to photodissociation is triphenylsulfonium triflate. See more Photoacids are molecules which become more acidic upon absorption of light. Either the light causes a photodissociation to produce a strong acid or the light causes photoassociation (such as a ring forming reaction) … See more An example due to photodissociation is triphenylsulfonium triflate. This colourless salt consists of a sulfonium cation and the triflate anion. … See more An example of a photoacid which undergoes excited-state proton transfer without prior photolysis is the fluorescent dye pyranine (8-hydroxy-1,3,6-pyrenetrisulfonate … See more WebThis study qualitatively and quantitatively characterized photoresist outgassing upon irradiation with 193 nm (DUV), 103.3 nm (VUV), 13.5 nm (EUV), and 6.7 nm (BEUV) synchrotron light.The photoresist samples used were polymethylmethacrylate (PMMA), poly(4-hydroxystyrene-co-tertbutylacrylate) (HS-TBA) and an EUV model resist denoted as …

WebAbstract: The triphenylsulfonium bromide was synthesized from the original reactant biphenyl sulfoxide with the improvement of the solvent medium. The reaction time was greatly shortened and its yield was boosted. Then the photoacid generator(PAG) triphenylsulfonium tosylate was synthesized by silver salt replacement.
