Ruthenium tris bipyridine derivatives and their photocatalytic activity in [4 + 2] cycloadditions. An experimental and DFT study

Synthesis and characterization of a ruthenium-containing copolymer for use as a photoredox catalyst

“…Absorption peaks were observed at wavelengths of 329, 344, and 457 nm, which are similar to those observed in pyrenemethanol (328 and 344 nm) 31 and [Ru(bpy) 2 (dmbpy)](PF 6 ) 2 (455 nm). 32 We investigated the photophysical properties of each of the Ru(II) species used in this study, namely, poly[Ru(bpy) 2 (dmbpy)…”

Sintesis, Pencirian Spektroskopi dan Sifat Fotomangkin Rutenium(II) Bis(bipiridil)- 2-(1H-pirazol-3-il)piridi

“…Kompleks Ru(II) mempunyai ciri elektrokimia yang baik contohnya memiliki sifat redoks berbalik dan stabil (Eskelinen et al 2000;Rozenel et al 2017). Kompleks Ru(II) biasa digunakan sebagai fotomangkin dalam tindak balas kimia kerana ia memiliki kuasa pengoksidaan dan penurunan yang baik di bawah sinaran cahaya (Prier et al 2013).…”
