Fluorene

Fluorene, also known as 9H-Fluorene, is a high-quality, versatile polycyclic aromatic hydrocarbon widely used as a key building block in advanced materials, pharmaceuticals, organic electronics, and specialty chemicals.

Technical Specifications

Packaging and Storage

• Net weight 25kg fiber drum.

• Keep container tightly closed in a dry place.

Primary Applications and Uses

Fluorene serves as a critical precursor and intermediate in multiple high-value industries due to its structural rigidity, planarity, and reactivity at the 9-position:

Organic Electronics & Optoelectronics:

Core building block for polyfluorene polymers and derivatives used in organic light-emitting diodes (OLEDs), organic solar cells, and electroluminescent materials for displays, lighting, and flexible electronics.

Pharmaceuticals:

Precursor to fluorene-9-carboxylic acid and other derivatives for synthesizing drugs, including antihistamines, antipsychotics, anticancer agents, and protecting groups like Fmoc (9-fluorenylmethoxycarbonyl) in peptide synthesis.

Dyes and Pigments:

Used to produce stable, vibrant dyes for textiles, plastics, inks, and specialty colorants via condensation reactions.

Polymers and Materials Science:

Ligands in metallocene catalysts (e.g., Kaminsky catalysts) for producing syndiotactic polypropylene; high-refractive-index materials, photoresists, and optical plastics.

Other Specialty Uses:

Synthesis of fluorenone derivatives for further nitration/commercial products; chemosensors and advanced functional materials.

Frequently Asked Questions (FAQs)

Q: What is Fluorene?

A: Fluorene is a polycyclic aromatic hydrocarbon (PAH) with formula C₁₃H₁₀, featuring a fused tricyclic structure. It is derived primarily from coal tar and used as a precursor in advanced chemistry.

Q: What are the main industrial uses of Fluorene?

A: It is primarily used in OLED materials, pharmaceutical intermediates (e.g., Fmoc protecting groups), dyes/pigments, polymer catalysts, and high-performance optical materials.

Q: Is Fluorene the same as Fluorine?

A: No. Fluorene is a hydrocarbon (C₁₃H₁₀) named for its violet fluorescence; it contains no fluorine atoms.

Q: Is Fluorene soluble in water?

A: No, it is practically insoluble in water but highly soluble in organic solvents like acetone, ethanol, and benzene.

Q: What is the difference between Fluorene and Fluorenone?

A: Fluorene is the parent hydrocarbon; fluorenone is its oxidized derivative (with a carbonyl at position 9), used in further syntheses.

Q: How should Fluorene be stored?

A: Store in a cool, dry place in tightly sealed containers, away from strong oxidants and light to preserve purity.

Q: Is Fluorene hazardous to health or the environment?

A: It may cause mild irritation and is toxic to aquatic organisms. Use proper handling and disposal practices per local regulations.
