Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, ACS Applied Polymer Materials called High-Frequency Swelling/Deswelling Oscillation of Poly(Oligoethylene Glycol) Methacrylate-Based Hydrogel Microspheres with a Tris(2,2′-bipyridyl)ruthenium Catalyst, Author is Inui, Kohei; Saito, Ikuma; Yoshida, Ryo; Minato, Haruka; Suzuki, Daisuke, which mentions a compound: 60804-74-2, SMILESS is F[P-](F)(F)(F)(F)F.F[P-](F)(F)(F)(F)F.C1(C2=NC=CC=C2)=NC=CC=C1.C3(C4=NC=CC=C4)=NC=CC=C3.C5(C6=NC=CC=C6)=NC=CC=C5.[Ru+2], Molecular C30H24F12N6P2Ru, Recommanded Product: Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate).
The swelling/deswelling oscillation of autonomously oscillating hydrogel microspheres (microgels) at a frequency close to that of the human heartbeat was accomplished. In this study, poly(oligoethylene glycol) methacrylate (pOEGMA)-based microgels that contain a tris(2,2′-bipyridyl)ruthenium catalyst were used to create oscillatory chem. systems via the Belousov-Zhabotinsky (BZ) reaction. The oscillating pOEGMA microgels can undergo the BZ reaction without irreversible aggregation at elevated temperatures or high substrate concentrations By optimizing the chem. composition of the microgels and the BZ reaction conditions, a short swelling/deswelling oscillation period of ~1.3 s was achieved in the dispersed state. Furthermore, in the assembled state, the microgels exhibited fast swelling/deswelling on the order of seconds (oscillation period: ~6.2 s). The central concept of this study, i.e., “”high-frequency oscillation””, can be expected to benefit the development of advanced bioinspired actuators that imitate the human heartbeat.
