Kang, Tae Woong; Tamura, Atsushi; Arisaka, Yoshinori; Yui, Nobuhiko published their research in Polymer Chemistry in 2021. The article was titled 《Visible light-degradable supramolecular gels comprising cross-linked polyrotaxanes capped with trithiocarbonate groups》.Recommanded Product: ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V) The article contains the following contents:
Visible light-degradable supramol. gels were designed using polyrotaxanes (PRXs) containing bulky trithiocarbonate groups as stopper mols. that are cleaved by visible light irradiation Visible-light-degradable PRXs comprise poly(ethylene glycol) (PEG) threaded through multiple α-cyclodextrins, where both terminals of the PEG axis were capped with bulky trithiocarbonate groups. The synthesized PRXs did not degrade in the dark. Irradiation with UV (UV; 365 nm, 7.03 mW cm-2) and visible light (465 nm, 44.5 mW cm-2) induced cleavage of the trithiocarbonate groups, and the α-cyclodextrins were dethreaded from the axial chain, demonstrating the photodegradability of PRXs capped with trithiocarbonate groups. Visible light-degradable supramol. gels were prepared by crosslinking PRXs with hexamethylene diisocyanate. The supramol. gels were degraded and disappeared upon irradiation with both UV and visible light due to photodegradation of PRXs. Visible light degradable supramol. gels are considered to be a new type of photodegradable material that can circumvent the potential phototoxicity of UV light to be applicable for alternative photodegradable biomaterials. The experimental process involved the reaction of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Recommanded Product: ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V))
((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6) is a peptide coupling reagent. Can be used in the preparation of phenyl esters of amino acids which have been shown to be valuable as blocked derivatives of amino acids in the field of peptide synthesis.Recommanded Product: ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)
