In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Probing charge transfer processes at p-GaAs electrodes under weak optical excitation, published in 2019-09-01, which mentions a compound: 60804-74-2, Name is Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), Molecular C30H24F12N6P2Ru, Synthetic Route of C30H24F12N6P2Ru.
The p-GaAs photocathode/acetonitrile interface was characterised in the dark and with tens of μW/cm2 laser powers at 830 nm wavelength, using cyclic voltammetry (CV) and electrochem. impedance spectroscopy (EIS). Two redox mediators were used that present completely different behaviors under low optical excitation: one (Tris(2,2′-bipyridine)ruthenium(II) hexafluorophosphate) is sensitive to the surface states of the photo-cathode and the other (benzoquinone) is not. The combined electrochem. methods allow us to characterize the energetics of the electrode-electrolyte interface as well as the dominant electron transfer process.
Although many compounds look similar to this compound(60804-74-2)Synthetic Route of C30H24F12N6P2Ru, numerous studies have shown that this compound(SMILES: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]), has unique advantages.
