In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Photochemical H2 evolution from water catalyzed by a dichloro(diphenylbipyridine)platinum(II) derivative tethered to multiple viologen acceptors, published in 2016, which mentions a compound: 15227-42-6, mainly applied to photocatalyst hydrogen water dichlorodiphenylbipyridine platinum viologen, Recommanded Product: cis-Dichlorobis(pyridine)platinum(II).
A new single-component photocatalyst for the reduction of water to H2, a dichloro(dpbpy)platinum(II) derivative (dpbpy = 4,4′-diphenyl-2,2′-bipyridine) tethered to four pendant viologen acceptors (1), is shown to exhibit twice higher photocatalytic efficiency than the previously reported dichloro(bpy)-platinum(II) analog (2; bpy = 2,2′-bipyridine), consistent with the higher absorptivity of 1 at the metal-to-ligand charge transfer (1MLCT) band due to the larger π-conjugation in dpbpy relative to bpy.
As far as I know, this compound(15227-42-6)Recommanded Product: cis-Dichlorobis(pyridine)platinum(II) can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
