Allgemeine Beschreibung
Iridium is a rare and dense transition metal that belongs to the platinum group of metals and is known for its remarkable physical and chemical properties. Iridium is used in high-temperature applications such as crucibles for crystal growth and in devices that operate under extreme conditions due to its high melting point and stability at elevated temperatures. It is also used in electrical contacts and electrodes because of its excellent corrosion resistance and electrical conductivity. In addition, iridium is used as a catalyst in various organic reactions including hydrogenation, water splitting, C-C coupling, and olefin metathesis.
Anwendung
- Iridium-based double perovskites for efficient water oxidation in acid media: This study highlights the development of iridium-based double perovskites that reduce iridium content while maintaining high activity and stability for water oxidation, significant for energy-related applications in material science (Diaz-Morales et al., 2016).
- Recent advances in understanding oxygen evolution reaction mechanisms over iridium oxide: This paper provides insights into the oxygen evolution reaction (OER) mechanisms on iridium oxide, crucial for improving catalytic processes in industrial applications (Naito et al., 2021).
- Iridium oxide fabrication and application: A review: A comprehensive review that discusses various methods for the fabrication of iridium oxides and their applications, particularly in sensors and catalysts, relevant to both drug discovery and material science (Chen et al., 2020).

The cellular behavior and toxicity effect of organometallic complexes depend largely on their peripheral ligands. In this study, we have synthesized a series of novel luminescent cationic iridium(III) complexes by tuning the ancillary N(∧)N ligand based on a structure [Ir(ppy)2(N(∧)N)](+)

A cationic Ir(I) complex-catalyzed O-to-N-alkyl migration in 2-alkoxypyridines bearing a secondary alkyl group on the oxygen atom by C-O bond cleavage is described. The present transformation gave various N-alkylpyridones in moderate to good yields. The addition of sodium acetate played
