Triphenylsulfonium nonaflate
WebTriphenylsulfonium nonaflate was prepared by metathesis. Potassium nonaflate, 6.6 g, and triphenylsulfonium bromide, 6.7 g, were partitioned between 30 ml nitromethane and 30 ml de-ionized water by vigorously stirring the two-phase mixture for one hour. The organic phase was then separated, Webtriphenylsulfonium nonaflate photoacid generator (30 trnol/g of polymer), and the photodecomposable base (trimethylsulfonium hydroxide as a 1% methanol solution, 22.4 rnole-% of' the PAG), in ...

WebAbstract The spectral effects were investigated in the transformations of the photoinitiator of the cationic polymerization of epoxide compounds, i.e., triphenylsulfonium hexafluorophosphate (TSHP), in the solid state (in a tablet with potassium bromide), in propylene oxide, and in its oligomer. WebThe products from the 193 nm irradiation of triphenylsulfonium nonaflate (TPS) embedded in a poly (methyl methacrylate) (PMMA) film have been characterized. The analysis of the photoproduct formation was performed using chromatographic techniques including HPLC, GPC and GC-MS as well as UV-vis and NMR spectroscopic methods.
WebApr 1, 2009 · Further studies using ToF SIMS to profile the distribution of PAG in the resist thin films revealed that the two PAGs focused on in this work, a triphenylsulfonium triflate (TPS.OTF) and a triphenylsulfonium nonaflate (TPS.ONF), exhibited very different distribution behavior in resist thin films. WebDec 22, 2024 · PHS and TPS-nf are a typical backbone polymer (a dissolution agent) and a typical acid generator of chemically amplified resists, respectively. The water intake and dissolution of PHS film with TPS-nf became fast with increasing UV exposure dose.
