Phosphine Oxide Derivative as a Passivating Agent to Enhance the Performance of Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Hiroyuki Kanda, Aron Joel Huckaba, Valentin Ianis Emmanuel Queloz, Albertus Adrian Sutanto, Hobeom Kim, Cansu Igci

Defects of metal-halide perovskites detrimentally influence the optoelectronic properties of the thin film and, ultimately, the photovoltaic performance of perovskite solar cells (PSCs). Especially, defect-mediated nonradiative recombination that occurs at ...

Development of Catalytic Asymmetric C-H Functionalizations with Chiral Cyclopentadienyl Iridium(III) Complexes

Yun-Suk Jang

Cp*Ir(III) catalyzed C-H functionalization is a growing field, since it provides novel complementary reactivities, but enantioselective C-H functionalization reactions with this metal remain a niche. This thesis investigates CpXIr(III) catalyzed asymmetric ...

Access to P- and Axially Chiral Biaryl Phosphine Oxides by Enantioselective (CpIrIII)-Ir-x-Catalyzed C-H Arylations

Nicolai Cramer, Julia Pedroni, Yun-Suk Jang

An enantioselective C-H arylation of phosphine oxides with o-quinone diazides catalyzed by an iridium(III) complex bearing an atropchiral cyclopentadienyl (Cp-x) ligand and phthaloyl tert-leucine as co-catalyst is reported. The method allows access to a) P ...

Cooperative Effects between Chiral Cp-x-Iridium(III) Catalysts and Chiral Carboxylic Acids in Enantioselective C-H Amidations of Phosphine Oxides

Nicolai Cramer, Yun-Suk Jang, Michael Christian Dieckmann

An enantioselective C-H amidation of phosphine oxides by using an iridium(III) catalyst bearing an atropchiral cyclopentadienyl (Cp-x) ligand is reported. A very strong cooperative effect between the chiral Cp-x ligand and a phthaloyl tert-leucine enabled ...

Metal Phosphorus Complexes as Antitumor Agents

Paul Joseph Dyson, Alexey Nazarov

Phosphorus-based ligands are an extremely important class of ligand and they have found many applications, especially in homogeneous catalysis. In addition, a phosphine ligand is found in a gold drug used to treat rheumatoid arthritis. Since metal compound ...

Synthesis and anticancer activity of chalcogenide derivatives and platinum(II) and palladium(II) complexes derived from a polar ferrocene phosphanyl-carboxamide

Paul Joseph Dyson, Anna Katherine Renfrew

The polar phosphinyl carboxamide, 1'-(diphenylphosphino)-1-[N-(2-hydroxyethyl)carbamoyl]ferrocene [I; Z = null; (1)] , reacts readily with H2O2 and elemental S to give the corresponding phosphine oxide I [Z = O (2)] and phosphine sulfide I [Z = S (3)], res ...
