“…[11][12][13]15 2-Cyanoprop-2-yl-1-dithionaphthalate (CPDN) was synthesized and used as the RAFT chain transfer agent (CTA) in this research, because it is an effective CTA for the polymerization of methacrylate monomers. 28,[31][32][33] The influence of different monomer reactivities and different polymerization methods on the composition variation was postulated by studying conversion and composition changes with respect to polymerization time. In addition, the effect of different polymer homogeneities on lithographic performance was studied.…”

ArF photoresist polymers were prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization and free radical polymerization (FRP). Three methacrylates with lithographic functionalities including 2-ethyl-2-adamantyl methacrylate (EAdMA), α-gamma-butyrolactone methacrylate (GBLMA), and 3-hydroxy-1-adamantyl methacrylate (HAdMA), were used as monomer components and 2-cyanoprop-2-yl-1-dithionaphthalate (CPDN) was used as the chain transfer agent (CTA). In both polymerizations, the order of monomer reactivity was GBLMA>HAdMA>>EAdMA. This caused a composition gradient in RAFT polymerization as well as composition inhomogeneity in FRP. The polymers prepared by RAFT polymerization had lower molecular weight distributions and more uniform compositions. The improvement in molecular weight distribution and composition uniformity of the polymers prepared by RAFT polymerization should be beneficial for the ArF lithography process.

Ferrocenium salts can be easily obtained from ferrocene by either synthetic preparation or in situ reaction. The ferrocenium ion can act as a one-electron oxidant and thus initiate or promote a range of radical processes. Ferrocene itself can donate electrons to suitable substrates, resulting in useful transformations. Ferrocenium salts can also act as mild Lewis acids. This paper highlights various uses of ferrocenium ions in organic reactions. 1 Introduction 2 Ferrocenium Salts as Lewis Acids 3 Ferrocenium Salts as One-Electron Oxidants 4 Ferrocene as an Electron Donor 5 Catalysis with Other Ferrocenium Derivatives 6 Conclusions

This tutorial review summarizes recent progress in the research field of controlled/"living" radical polymerization (CLRP) from Soochow University. The present paper gives a broad overview of the mechanism study and molecular design in CLRP. The mechanism study in CLRP aided by microwave, initiated by -radiation at low temperature, mediated by iron, in reversible addition-fragmentation chain transfer (RAFT) polymerization and the mechanism transfer between different CLRP processes are reviewed and summarized. The molecular design in CLRP, especially in RAFT polymerization for mechanism study, and in achieving tailor-made functional polymers is studied and discussed in the later part.controlled/"living" radical polymerization, atom transfer radical polymerization, reversible addition-fragmentation chain transfer polymerization, molecule design, mechanism study
