Description

2,3-Bis(4-(Phenyl(4-(1,2,2-Triphenylvinyl)Phenyl)Amino)Phenyl)Fumaronitrile is a high-performance organic semiconductor material belonging to the class of thermally activated delayed fluorescence (TADF) emitters. This compound matters for its exceptional ability to convert nearly 100% of electrical energy into light, enabling the development of highly efficient and stable organic light-emitting diodes (OLEDs). It is critically needed by manufacturers and R&D teams in the display and solid-state lighting industries seeking to create next-generation, energy-saving devices with superior color purity.

Application

• OLED Emitter Layer: As a core TADF dopant material in the emissive layer of red or orange OLED displays and lighting panels.
• Phosphorescent OLED (PHOLED) Host Material: Serving as a host matrix for other phosphorescent dopants to improve efficiency and reduce efficiency roll-off.
• Academic and Industrial R&D: For fundamental research into photophysical properties, molecular design, and the development of novel TADF material systems.
• Printed Electronics: Potential use in solution-processable OLED inks for cost-effective, large-area fabrication of flexible displays.
• Lighting Applications: Development of high-efficiency, low-heat generation solid-state lighting sources for commercial and residential use.
• Sensor Technology: Exploration in chemical sensors or bio-imaging probes leveraging its sensitive luminescent properties.

Quality Control

Our 2,3-Bis(4-(Phenyl(4-(1,2,2-Triphenylvinyl)Phenyl)Amino)Phenyl)Fumaronitrile is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity, critical for OLED device performance. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and key impurity profiles. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify the material meets the exacting standards required for electronic grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry place. This material is light-sensitive and easily oxidized; prolonged exposure to air or light may degrade its optoelectronic properties.
