4-FLUORO-PHENETHYLAMMONIUM CHLORIDE 4FPEACL 99% CAS 459-19-8

RESEARCH GRADE MATERIAL

Product Overview
4-Fluoro-Phenethylammonium Chloride (4FPEACl, CAS 459-19-8) is a modified organic chloride salt with 4FPEACl 99% purity, designed as a specialized perovskite solar cell fabrication precursor. This compound functions as a perovskite surface energy modulator, where the electron-withdrawing fluorine substituent on the aromatic ring modulates the film surface energy level while simultaneously passivating grain boundary defects. The combined electronic and structural passivation effects enhance both the stability and optoelectronic output performance of perovskite devices. Supplied as the chloride salt variant, 4FPEACl enables halide composition engineering alongside surface modification in 2D and quasi-2D perovskite systems. With purity exceeding 99% and stable batch-to-batch quality, this precursor ensures experimental data reproducibility and optimal device performance. Compatible with spin-coating and precursor solution blending thin-film preparation techniques, the product requires strict light-sensitive hygroscopic dry storage to maintain material integrity.

APPLICATION SCOPE: Surface energy level modulator for perovskite solar cell thin films through fluorine-functionalized passivation. Grain boundary defect passivation agent with combined electronic and structural passivation mechanisms. Halide composition engineering precursor for 2D and quasi-2D perovskite systems requiring chloride incorporation. Stability and optoelectronic performance enhancement additive for photovoltaic and photodetector devices. Compatible with spin-coating and precursor solution blending deposition protocols. Supports university and research institute laboratory research on perovskite photovoltaics and optoelectronic detection.
PACKAGING: This listing is for the 5 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The hygroscopic nature of 4-fluoro-phenethylammonium chloride necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: 4-Fluoro-Phenethylammonium chloride is strongly hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or alkaline reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the material within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). Refer to SKU MS600720 for ordering and documentation purposes. For detailed safety and handling information, consult the Safety Data Sheet prior to use.

This compound is strongly hygroscopic and light-sensitive, requiring strict moisture and light protection to prevent deliquescence and hydrolysis. Storage must be in a sealed, light-protected container under inert atmosphere at room temperature, away from strong oxidizing agents and alkaline reagents.

  • Moisture Sensitivity: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.
  • Light Sensitivity: Photodegradation occurs upon exposure to light; store in light-protective packaging at all times.
  • Inert Atmosphere Requirement: All precursor solution preparation must be performed inside an inert-atmosphere glovebox with H₂O below 1 ppm and O₂ below 1 ppm.
  • Chemical Compatibility: Do not store together with strong oxidizing agents or alkaline reagents to avoid hazardous reactions.
  • Post-Use Sealing: Tighten the container cap immediately after each use to prevent moisture ingress from ambient air.

This procedure outlines the steps to safely handle the hygroscopic and light-sensitive material and prepare precursor solutions under inert conditions. Strict adherence to moisture and light protection protocols ensures material integrity and experimental reproducibility.

Required Equipment: Inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm), Light-protective storage container, Clean spatula

  1. Transfer to Storage
    Transfer the received material immediately to a desiccated, light-protected storage environment at room temperature.
  2. Equilibrate Container
    Allow the sealed container to equilibrate to room temperature inside the glovebox antechamber before opening.
  3. Open Under Inert Atmosphere
    Open the container only inside the inert-atmosphere glovebox to prevent moisture and oxygen exposure.
  4. Weigh and Dispense
    Weigh the required amount using a clean spatula and transfer directly into a precursor solution vial.
  5. Reseal Container
    Immediately tighten the container cap after dispensing to maintain an airtight seal.
  6. Return to Storage
    Return the container to the light-protected, moisture-free storage area away from oxidizing agents and alkaline reagents.

How does the fluorine substituent in 4FPEACl enhance perovskite solar cell performance compared to non-fluorinated phenethylammonium chloride?

The electron-withdrawing fluorine substituent modulates the perovskite film surface energy level, providing an additional electronic tuning parameter beyond structural passivation. This optimizes energy level alignment and charge extraction efficiency while the ammonium head group passivates grain boundary defects, delivering synergistic passivation effects that enhance both stability and optoelectronic output performance.

What are the critical storage and handling conditions required to maintain 4FPEACl integrity?

4FPEACl is strongly hygroscopic and light-sensitive. It must be stored in a light-protected, dry, sealed container at room temperature. After each use, tighten the cap immediately to prevent moisture ingress. For precursor solution preparation, handle within an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm to avoid deliquescence and hydrolysis that irreversibly degrade precursor stoichiometry.

Can 4FPEACl be used for halide composition engineering in 2D perovskite systems?

Yes, as the chloride salt variant in the fluoro-phenethylammonium series, 4FPEACl enables halide composition flexibility alongside surface modification in 2D and quasi-2D perovskite systems. This supports multi-dimensional compositional optimization strategies for tuning optoelectronic properties in photovoltaic and photodetector devices.

4-Fluoro-Phenethylammonium Chloride (4FPEACl) is a high-purity perovskite surface energy modulator offering fluorine-functionalized passivation for enhanced stability and optoelectronic performance, but requires strict inert-atmosphere handling and light-protected, dry storage to prevent moisture-induced degradation.
