Description

3-Ethynylperylene is a high-purity, functionalized polycyclic aromatic hydrocarbon (PAH) derivative, identified by CAS NO 132196-66-8. This compound is valued for its unique optoelectronic properties derived from its extended conjugated π-system and terminal alkyne group, which serves as a versatile handle for further chemical modification. It is a critical building block for researchers and manufacturers in the fields of organic electronics and advanced material science, enabling the development of next-generation devices.

Application

• Organic Light-Emitting Diodes (OLEDs): Serves as a core component or dopant in emissive layers for high-efficiency displays and lighting.
• Organic Photovoltaics (OPVs): Used as an electron donor or acceptor material in the active layer of solar cells.
• Organic Field-Effect Transistors (OFETs): Functions as a semiconducting material for high-mobility electronic circuits.
• Chemical Synthesis & Conjugation: The ethynyl group allows for Sonogashira coupling and click chemistry to create complex molecular architectures and polymers.
• Fluorescent Probes & Sensors: Utilized in the design of highly sensitive and selective detection systems due to its strong fluorescence.
• Liquid Crystals & Nanomaterials: Acts as a rigid, planar core for constructing discotic liquid crystals or carbon-based nanomaterials.

Quality Control

Our 3-Ethynylperylene is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including HPLC, NMR, and GC-MS, to verify chemical identity and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your R&D and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. For long-term storage under inert atmosphere (e.g., argon or nitrogen) is recommended to maintain optimal stability.
