Journal ArticleDOI
Solution deposited NiO thin-films as hole transport layers in organic photovoltaics
K. Xerxes Steirer,K. Xerxes Steirer,Jordan Chesin,N. Edwin Widjonarko,N. Edwin Widjonarko,Joseph J. Berry,Alex Miedaner,David S. Ginley,Dana C. Olson +8 more
TL;DR: In this paper, a nickel metal organic ink precursor is used to fabricate NiO hole transport layers on indium tin oxide anodes, which achieves similar OPV device results reported with NiO films from PLD as well as PEDOT:PSS.
Journal ArticleDOI
Nature of hydrogen interactions with Ni(II) complexes containing cyclic phosphine ligands with pendant nitrogen bases
Aaron D. Wilson,Richard K. Shoemaker,Alex Miedaner,James T. Muckerman,Daniel L. DuBois,M. Rakowski DuBois +5 more
TL;DR: The nature of the isomers, together with calculations, suggests a mode of hydrogen activation that involves a symmetrical interaction of a nickel dihydrogen ligand with two amine bases in the diphosphine ligands.
Journal ArticleDOI
[Ni(Et2PCH2NMeCH2PEt2)2]2+ as a Functional Model for Hydrogenases
Calvin J. Curtis,Alex Miedaner,Rebecca Ciancanelli,William W. Ellis,Bruce C. Noll,M. Rakowski DuBois,Daniel L. DuBois +6 more
TL;DR: Oxidation of [HNi(PNP)(2)](PF(6)) has been studied by cyclic voltammetry, and the results are consistent with a rapid migration of the proton from the Ni atom of the resulting [H Ni-H bond dissociation free energies], which indicate that proton migration from Ni to N should be favorable by 1-2 pK(a) units.
Journal ArticleDOI
Measurement of the hydride donor abilities of [HM(diphosphine)2]+ complexes (M = Ni, Pt) by heterolytic activation of hydrogen.
TL;DR: The reactivity of the various [M(diphosphine)2]2+ complexes toward hydrogen parallels their measured hydride acceptor abilities.
Journal ArticleDOI
Electrochemical Reduction of CO2 Catalyzed by Small Organophosphine Dendrimers Containing Palladium
TL;DR: In this article, the sequential addition of diethyl vinylphosphonate to primary phosphines followed by reduction with lithium aluminum hydride can be used to synthesize small dendrimers containing up to 15 phosphorus atoms.
