Recent photo- and radiation chemical studies of sulfur radical cations

Recent photo- and radiation chemical studies have significantly increased our knowledge about sulfur radical cations, with a focus on their fragmentation reactions and role in biochemical oxidation processes of amino acids and peptides.

Thioxanthone based water-soluble photoinitiators for acrylamide photopolymerization

Thioxanthone-based water-soluble photoinitiators can efficiently initiate acrylamide photopolymerization in water, with 2A being more efficient than 1A.

Formation of cation–radical anion pairs derived from carboxybenzophenone–tetrabutylammonium salts. Pulse radiolysis studies

Pulse radiolysis of carboxybenzophenone-tetrabutylammonium salts allows for direct reduction of benzophenone radical anion, resulting in cation-radical anion pairs with improved spectra and kinetic parameters compared to photochemistry.

Benzophenone‐(phenylthio)acetic acid phosphonium salts as initiators of free‐radical photopolymerization of vinyl monomers: Mechanistic studies

Benzophenone-sensitized photooxidation of phosphonium salts of (phenylthio)acetic acid enables faster free-radical photopolymerization of vinyl monomers, with rates more than twice those found for direct initiation by benzophenone and the benzophen
