Semiconductor Display Materials

 

Section	Details
Chemical Structure	Name: 4-Ethyl-2.6-difluorophenylpropyl phenylacetylene Formula: C₂₅H₂₂F₂ CAS No.: 221526-72-3 Molecular Weight: 360.44 g/mol Structure: Biphenyl derivative with ethyl substitution at C4. fluorine at C2/C6. and phenylacetylene linker.
Physical Properties	Boiling Point: 459.4±45.0 °C (predicted) Density: 1.14±0.1 g/cm³ (predicted) Solubility: Likely hydrophobic due to fluorine substitution (specific data unavailable).
Chemical Properties	Stability: Fluorination enhances thermal and chemical stability. Reactivity: Fluorine substituents reduce nucleophilicity but may allow electrophilic aromatic substitution under harsh conditions.
Synthesis Methods	Likely involves cross-coupling reactions (e.g., Suzuki-Miyaura) or nucleophilic substitutions to link the fluorinated phenyl ring with the phenylacetylene group. Specific protocols require further literature review.
Applications	Pharmaceuticals: Intermediate for synthesizing fluorinated drugs (e.g., antifungals, anti-inflammatories). Materials Science: Potential use in liquid crystals or electronic materials due to fluorination-induced anisotropic properties. Research: Model compound to study fluorine effects on molecular conformation, metabolic stability, and membrane permeability.
Supplier Information	Commercially available from multiple vendors (e.g., T&W GROUP, Xi’an Ruilian) in purities ≥95%, with packaging from 1g to 5kg.
