Description

Ir(Mppz)2(Acac) CAS NO 939959-64-5 is an organometallic iridium(III) complex featuring cyclometalated 3-methyl-1-phenyl-1H-pyrazole (Mppz) and acetylacetonate (acac) ligands. This compound is a critical high-performance material valued for its exceptional photophysical properties, including high phosphorescence quantum yield and color purity. It is primarily utilized by manufacturers and researchers in the organic light-emitting diode (OLED) industry for the development of efficient red and near-infrared emitters in display and lighting technologies.

Application

• OLED Emitter Material: As a phosphorescent dopant in the emissive layer of OLED devices for displays (smartphones, TVs) and solid-state lighting.
• Red/NIR Emitter Synthesis: A key precursor or active component in synthesizing red and near-infrared emitting materials for specialized optoelectronic applications.
• Photophysical Research: Used in academic and industrial R&D to study triplet harvesting, energy transfer mechanisms, and novel electroluminescent systems.
• Sensors and Bio-imaging: Potential application in the development of phosphorescent sensors and probes for oxygen sensing or biological imaging due to its long-lived excited state.
• Light-Emitting Electrochemical Cells (LECs): As an emissive material in solution-processable LEC devices.

Quality Control

Our Ir(Mppz)2(Acac) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for optoelectronic device performance. Each lot undergoes comprehensive analytical characterization, including HPLC for purity and 1H/13C NMR and mass spectrometry for structural confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry place at 2-8°C to minimize oxidation and degradation. The material is hygroscopic (moisture-sensitive) and easily oxidized (store under inert atmosphere); ensure containers are sealed immediately after use.
