Semiconductor Display Materials

1. Physicochemical Properties

• CAS Number: 95759-59-4
• Molecular Formula: C₂₅H₂₇F
• Molecular Weight: 346.48 g/mol
• Boiling Point: 472.37°C
• Density: 1.021 g/cm³
• Flash Point: 267.27°C
• Structure: A terphenyl structure with a 2′-fluoro substitution and a 4-pentyl substitution on one benzene ring, and an ethyl group attached to the 4”-position of another benzene ring.

Key Characteristics:

The fluoro and pentyl substitutions influence the compound’s polarity and solubility.

The terphenyl structure contributes to conjugated π-systems, potentially useful in optoelectronic applications.

2. Synthesis Method

The compound is likely synthesized via Suzuki coupling reactions or similar cross-coupling methodologies. This involves reacting a fluoro-substituted aryl halide with a pentyl-substituted arylboronic acid or similar nucleophile. The synthesis may require:

• Palladium catalysts to facilitate the coupling.
• Purification via chromatography or recrystallization to achieve high purity.

3. Applications

• Liquid Crystals: The terphenyl structure and fluoro substitution make it a candidate for liquid crystal materials, where it could influence molecular alignment and optical properties.
• Organic Electronics: Potential use in organic light-emitting diodes (OLEDs) or organic field-effect transistors (OFETs) due to its conjugated structure and electron-withdrawing fluoro atom.
• Specialty Coatings: The hydrophobic nature and thermal stability may be useful in advanced surface coatings or films.

4. Safety Information

• Handling: Follow standard chemical safety protocols (e.g., use gloves, goggles, and fume hoods). Avoid skin contact and inhalation.
• Storage: Keep in a cool, dry place, away from oxidants and strong acids.
• Disposal: Consult local regulations for hazardous waste disposal.
