Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 3211-76-5, Name is L-SelenoMethionine, molecular formula is , belongs to amides-buliding-blocks compound. In a document, author is Gui, Yong-Yuan, Name: L-SelenoMethionine.
The syntheses of zinc(II) tetra-[3-(4-phenoxy) (propanoic acid) phthalocyanine] (2) and zinc(II) mono[3-(4-phenoxy) (propanoic acid) phthalocyanine (3) are reported in this work. Compounds 2 and 3 were covalently linked to glutathione capped silver (AgNPs-GSH), gold (AuNPs-GSH) and silver-gold alloy (Ag(3)Au(1)NPs-GSH) nanoparticles (NPs) via an amide bond formation to afford the conjugates: 2-AgNPs-GSH, 3-AgNPs-GSH, 2-AuNPs-GSH, 3-AuNPs-GSH, 2-Ag(3)Au(1)NPs-GSH and 3-Ag(3)Au(1)NPs-GSH. The photophysicochemical behaviours of the compounds and their conjugates with NPs were assessed in solution. The conjugates afforded a decrease in fluorescence quantum yields and lifetimes with improved triplet quantum yields in comparison to the compounds. Accordingly, the AgNPs and AuNPs conjugates with the compounds afforded high singlet quantum yields. On the contrary, the conjugates of the alloy afforded decreased singlet quantum yields probably due to the screening effect. The compounds and their conjugates with NPs could serve as a viable and efficacious photosensitizer for photodynamic therapy. (C) 2017 Elsevier B.V. All rights reserved.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3211-76-5, in my other articles.
