Description

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.

  • Chloride Salt Variant for Halide Engineering: As the chloride-based analog in the fluoro-phenethylammonium series, this precursor enables halide composition flexibility alongside surface modification in 2D and quasi-2D perovskite systems, supporting multi-dimensional compositional optimization strategies.
  • Stable Batch-to-Batch Reproducibility: With purity exceeding 99% and rigorous quality control, the precursor ensures consistent experimental data reproducibility and optimal device performance across extended research programs and multi-institutional collaborative studies.

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 material is strongly hygroscopic and light-sensitive, requiring strict moisture- and light-protected storage to prevent irreversible degradation. Handling must be performed under inert atmosphere conditions to maintain precursor stoichiometry and prevent hydrolysis.

  • Environmental Sensitivity: Store in a light-protected, dry, sealed container at room temperature to prevent photodegradation and moisture ingress.
  • Infrastructure Requirement: Prepare precursor solutions within an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm.
  • Failure Mode: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.
  • Compatibility Constraint: Avoid storage with strong oxidizing agents or alkaline reagents due to potential reactivity.
  • Handling Procedure: Tighten the container cap immediately after each use to prevent moisture ingress from ambient air.

This material requires strict moisture and light protection to prevent degradation. The following steps outline the safe handling protocol for maintaining material integrity.

Required Equipment: Inert-atmosphere glovebox, Light-protective packaging, Desiccated storage container, Protective gloves

  1. Transfer to storage
    Transfer the material immediately to a desiccated, light-protected storage environment upon receipt.
  2. Prepare glovebox
    Confirm that the glovebox atmosphere is maintained at H₂O < 1 ppm and O₂ < 1 ppm before handling.
  3. Don protective equipment
    Wear protective gloves throughout all experimental procedures to avoid direct skin contact.
  4. Open container
    Open the container only inside the inert-atmosphere glovebox to prevent moisture exposure.
  5. Reseal container
    Tighten the container cap immediately after removing the required amount of material.
  6. Store properly
    Store the container in a light-protected, moisture-free environment away from strong oxidizing agents and alkaline reagents.

How does the fluorine substituent in 4-fluoro-phenethylammonium chloride affect perovskite surface energy level modulation compared to non-fluorinated analogs?

The electron-withdrawing fluorine substituent on the aromatic ring modulates the perovskite film surface energy level, providing an additional electronic tuning parameter beyond simple structural passivation. This allows optimization of device energy level alignment and charge extraction efficiency. The specific energy level shift relative to non-fluorinated phenethylammonium chloride is not quantified in the product description, but the fluorine functionalization is designed to enhance electronic tuning.

What glovebox conditions are required for handling 4-fluoro-phenethylammonium chloride during precursor solution preparation?

The material is strongly hygroscopic and light-sensitive. When preparing precursor solutions, handling must be performed within an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm to prevent moisture ingress and irreversible degradation of precursor stoichiometry. This requirement is explicitly stated in the product's important notice and handling instructions.

What are the critical storage conditions to prevent degradation of 4-fluoro-phenethylammonium chloride?

Store in a light-protected, dry, sealed container at room temperature. The compound is strongly hygroscopic and light-sensitive; exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Immediately transfer to a desiccated, light-protected environment upon receipt, and tighten the container cap after each use. Do not store with strong oxidizing agents or alkaline reagents.

4-Fluoro-Phenethylammonium Chloride (4FPEACl, 99%) serves as a perovskite surface energy modulator and grain boundary passivation agent, leveraging fluorine-functionalized electronic tuning and dual passivation mechanisms to enhance device stability and optoelectronic output. However, its strong hygroscopicity and light sensitivity demand rigorous anhydrous glovebox handling and light-protected storage to prevent irreversible degradation.

Trade-offs

  • Strict Anhydrous Glovebox Requirement: The material is strongly hygroscopic; precursor solution preparation must be performed in an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm to prevent deliquescence and irreversible degradation of stoichiometry.
  • Light-Sensitive and Hygroscopic Storage: The compound requires immediate transfer to a light-protected, desiccated environment upon receipt, and containers must be tightly sealed after each use to avoid moisture ingress; exposure to moisture or light causes photodegradation and hydrolysis.
