In 2022,Aoyama, Takuma; Kato, Kazuaki; Urayama, Kenji published an article in ACS Macro Letters. The title of the article was 《Marked Sensitivity of Ultimate Elongation to Loading Axiality in Polyrotaxane Gels with Largely Slidable Cross Links》.Formula: C12H22F6N6OP2 The author mentioned the following in the article:
Polyrotaxane (PR) gels with low ring densities have figure-of-eight crosslinks that can slide along network strands. The slidable crosslinks have a unique ability to increase the network strand length between adjacent crosslinks in the loading direction via chain supply from the stress-free direction, thereby enhancing the ultimate elongation (λm) of the gels. We reveal that this enhancement of λm due to the slidable crosslinks is pronounced specifically in uniaxial stretching while it is considerably modest in biaxial stretching. The sensitivity of λm to loading axiality becomes larger as the ring densities decreases. The corresponding difference in λm is markedly larger for the PR gels with low ring densities than that for the networks with fixed crosslinks. The exceptional sensitivity of λm to loading axiality unveils a previously unidentified aspect of the chain-supply mechanism based on slidable crosslinks. The results came from multiple reactions, including the reaction of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Formula: C12H22F6N6OP2)
((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6) is used as a reagent for peptide coupling, lactonization, selective esterification, amidation of alfa amino acids without racemization and synthesis of magnolamide for antioxidative activity and catalyst for 9-acridinecaroboxamide derivative. It acts as a substitute for (Benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP) reagent.Formula: C12H22F6N6OP2
