Uranyl Sulfoxide Complexes as Photoinitiators of Polymerization of Methyl Methacrylate and Epoxy Acrylate Oligomers

Structural diversity of uranyl acrylates

“…[2][3][4][5][6][7][8][9][10][11][12] Moreover, the uranyl cation endows its compounds with luminescent properties 13,14 and can initiate photochemical polymerization. [15][16][17][18][19] Particularly, uranyl salts serve as a photosensitizer in polymerization reactions of vinyl-containing monomers, such as methacrylic acid, 17 acrylonitrile, 18 methylmethacrylate, 18,19 etc. The interest in uranyl monocarboxylate complexes, both aliphatic and aromatic, has been rising in the past decade due to their use as models to mimic the interaction of the uranyl cation with the carboxylate groups of humic acids, which play an important role in migration of actinides in natural systems.…”

Uranyl Complexes with (Meth)acrylate Anions

“…Despite the stability of uranyl carboxylate complexes, compounds containing [UO 2 (CH 2 CHCOO) 3 ] – groups have recently been synthesized. The R[UO 2 (CH 2 CHCOO) 3 ] (R = K, NH 4 , Rb, or Cs) complexes18 exhibit nonlinear optical properties, but their synthesis is difficult due to the polymerization of the unsaturated acrylic acid by UV radiation in the presence of uranyl cations 19–21. These compounds are the only examples of uranyl (meth)acrylate compounds to have been studied structurally so far.…”
