Semiconductor Display Materials

1. Physicochemical Properties

• CAS Number: 132123-39-8
• Molecular Formula: C₂₁H₂₃F₃
• Molecular Weight: 332.4 g/mol
• Appearance: White crystalline solid.
• Purity: ≥99%.
• Structure: A biphenyl structure with 3.4.5-trifluoro substitution on one benzene ring and a trans-4′-propyl bicyclohexyl group attached to the other benzene ring.

Key Characteristics:

The propylbicyclohexyl group contributes to hydrophobic behavior and potential liquid crystalline properties.

The trifluoromethyl substitution enhances stability and electronic effects, influencing the material’s optical and electronic properties.

2. Synthesis Method

The compound is likely synthesized via Grignard reactions or similar methods. This involves reacting a bicyclohexyl-substituted aryl halide with a 3.4.5-trifluoro-substituted aryl Grignard reagent. The synthesis may require:

• Protection/deprotection steps to manage reactive sites.
• Purification via chromatography or recrystallization to achieve high purity.

3. Applications

• Pharmaceutical Intermediates: The compound is used as a pharmaceutical intermediate, suggesting applications in drug synthesis.
• Liquid Crystals: The bicyclohexyl structure and fluorine atoms 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 photovoltaic cells due to its conjugated structure and electron-withdrawing fluorine atoms.

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.
