A tetra-nickel-containing polyoxotungstate, Na6K4[Ni4(H2O)2(PW9O34)2]·32H2O (Na6K4-Ni4P2), has been synthesized in high yield and systematically characterized. The x-ray crystal structure confirms that a tetra-nickel cluster core [Ni4O14] is sandwiched by two trivacant, heptadentate [PW9O34]9- POM ligands. When coupled with (4,4′-di-tert-butyl-2,2′-dipyridyl)-bis(2-phenylpyridine(1H))-iridium(III) hexafluorophosphate [Ir(ppy)2(dtbbpy)][PF6] as photosensitizer and triethanolamine (TEOA) as sacrificial electron donor, the noble-metal-free complex Ni4P2 works as an efficient and robust mol. catalyst for H2 production upon visible light irradiation Under minimally optimized conditions, Ni4P2 catalyzes H2 production over 1 wk and achieves a turnover number (TON) of as high as 6500 with almost no loss in activity. Mechanistic studies (emission quenching, time-resolved fluorescence decay, and transient absorption spectroscopy) confirm that, under visible light irradiation, the excited state [Ir(ppy)2(dtbbpy)]+* can be both oxidatively and reductively quenched by Ni4P2 and TEOA, resp. Extensive stability studies (e.g., UV-vis absorption, FT-IR, mercury-poison test, dynamic light scattering (DLS) and transmission electron microscopy (TEM)) provide very strong evidence that Ni4P2 catalyst remains homogeneous and intact under turnover conditions.
There is still a lot of research devoted to this compound(SMILES：[F-][P+5]([F-])([F-])([F-])([F-])[F-].CC(C)(C1=CC=[N]([Ir+3]23([C-]4=CC=CC=C4C5=CC=CC=[N]25)([C-]6=CC=CC=C6C7=CC=CC=[N]37)[N]8=CC=C(C(C)(C)C)C=C98)C9=C1)C)Electric Literature of C40H40F6IrN4P, and with the development of science, more effects of this compound(676525-77-2) can be discovered.
