Hace 4 horas · The coordination of xanthate to the metal center in solution can lead to the formation of more stable complexes, promoting their precipitation and, consequently, easier removal from the environment. In addition, TD-DFT analysis in solution was carried out with the same solvent used in the experimental UV‒Vis analysis (n-hexane).
Hace 4 días · Reversible addition-fragmentation chain transfer polymerization (RAFT), coined MADIX for Macromolecular Design via the Interchange of Xanthates (MADIX) for the specific use of xanthate chain transfer agents, recently celebrated its 25th anniversary [1,2,3,4].Since its discovery, a significant amount of work has been performed on the design of new thiocarbonylthio chain transfer agents of the ...
14 de abr. de 2024 · Functionalization of these polyphenol compounds with xanthate group will greatly improve the binding capacity of soft heavy metal ions . Thus, in the present study, these xanthated persimmon (MPM) is utilized to assess the extraction of analytes from contaminated aqueous solutions.
Hace 3 días · In particular, the solution processing and cocasting with polymers allows for films with homogeneous mixtures of metal xanthate complex and the polymer of interest. (26−30) This has been used as a route to the creation of bulk heterojunction thin films containing a semiconducting polymer and metal chalcogenide nanocrystals for light harvesting.
