Description

4-FLUORO-PHENETHYLAMMONIUM IODIDE C₈H₁₁FIN 99% 4FPEAI CAS 1413269-55-2

RESEARCH GRADE MATERIAL

Product Overview
4-Fluoro-Phenethylammonium Iodide (C₈H₁₁FIN, 4FPEAI, p-F-PEAI, CAS 1413269-55-2) is a fluorine-substituted modified phenethyl organic iodide salt precursor with C₈H₁₁FIN 99% purity 4FPEAI, supplied as a white powder with a molecular weight of 267.08 g/mol and freely soluble in polar organic solvents including DMF and DMSO. This compound is specifically designed for 2D perovskite defect passivation and quasi-2D perovskite thin film fabrication. The para-fluorine substituent on the aromatic ring establishes a strong molecular dipole field that promotes charge dissociation at perovskite interfaces while simultaneously suppressing iodine vacancy formation, thereby dramatically reducing non-radiative recombination losses and extending carrier lifetime. The fluorine-substituted alkyl chain provides a hydrophobic barrier effect that significantly enhances both moisture and thermal stability of perovskite devices. Extensively purified with low impurity content and stable batch-to-batch experimental reproducibility, this precursor is compatible with spin-coating and precursor co-blending thin-film preparation techniques. The product requires light-sensitive hygroscopic glovebox storage—inert atmosphere protection with complete moisture exclusion is essential for maintaining material integrity.

Key Features & Advantages
  • Strong Molecular Dipole Field for Charge Separation Enhancement: The para-fluorine substituent establishes a pronounced molecular dipole moment that facilitates exciton dissociation and charge carrier separation at perovskite interfaces, directly contributing to improved photocurrent generation and reduced recombination losses.
  • Iodine Vacancy Suppression for Defect Density Reduction: The electron-withdrawing fluorine group stabilizes the local chemical environment, effectively suppressing iodine vacancy formation—a primary source of non-radiative recombination centers—thereby significantly extending carrier lifetime in passivated perovskite films.
  • Enhanced Moisture and Thermal Stability via Hydrophobic Barrier: The fluorine-substituted aromatic ring provides a robust hydrophobic barrier that repels moisture penetration while maintaining structural integrity under thermal stress, delivering simultaneous humidity and temperature stability improvements.
  • Stable Batch-to-Batch Reproducibility: Extensively purified with >99% purity and low impurity content, the precursor ensures consistent experimental data reproducibility and reliable device performance across extended research programs and multi-batch experimental designs.

APPLICATION SCOPE: Fluorine-functionalized organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Surface and grain boundary defect passivation agent with dipole-enhanced charge separation. Iodine vacancy suppression precursor for reducing non-radiative recombination losses. Hydrophobic barrier additive for moisture-resistant perovskite optoelectronic devices. Compatible with 2D/3D stacked perovskite solar cells, photodetectors, and perovskite light-emitting diodes. Supports university and research institute laboratory research on high-stability perovskite devices where defect passivation and environmental resistance are experimental priorities.
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 strongly hygroscopic nature of 4-fluoro-phenethylammonium iodide necessitates immediate transfer to a desiccated, light-protected storage environment—preferably an inert-atmosphere glovebox for long-term storage. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: 4-Fluoro-Phenethylammonium iodide 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; avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Prioritize powder weighing and solution preparation within a nitrogen-filled glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For long-term storage, inert-atmosphere glovebox conditions are recommended. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. For detailed safety and handling information, consult the Safety Data Sheet prior to use.

This hygroscopic and light-sensitive compound requires strict exclusion of ambient moisture and light to prevent deliquescence and photodegradation. Storage and handling must be performed under inert atmosphere conditions (glovebox with H₂O and O₂ below 1 ppm) to maintain stoichiometric integrity.

  • Moisture Sensitivity: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.
  • Light Sensitivity: Photodegradation necessitates light-protected storage and handling in amber or foil-wrapped containers.
  • Glovebox Requirement: All weighing and solution preparation procedures must be conducted inside a nitrogen-filled glovebox with H₂O <1 ppm and O₂ <1 ppm.
  • Container Closure: The container cap must be tightened immediately after each use to prevent moisture ingress from ambient air.
  • Long-Term Storage: For extended periods, storage in an inert-atmosphere glovebox is recommended to preserve material quality.

This protocol describes the safe handling and storage procedures for the hygroscopic, light-sensitive perovskite precursor. Adherence to glovebox operations and moisture exclusion is critical to prevent material degradation.

Required Equipment: Inert-atmosphere glovebox (N₂, H₂O <1 ppm, O₂ <1 ppm), Light-protective packaging (amber glass vial or foil wrapping), Desiccated storage container, Protective gloves

  1. Transfer to Glovebox
    Transfer the sealed package to an inert-atmosphere glovebox immediately upon receipt to avoid moisture exposure.
  2. Inspect Material
    Inspect the powder for any signs of caking or discoloration before use, as deliquescence may have occurred if exposed to humidity.
  3. Weigh Under Inert Atmosphere
    Weigh the required amount inside the glovebox using a clean, dry spatula and transfer to a light-protected vial.
  4. Prepare Solution
    Prepare solutions by dissolving the powder in anhydrous DMF or DMSO under inert atmosphere, avoiding air exposure.
  5. Store Excess Material
    Store unused material in a tightly sealed container inside the glovebox, protected from light, for long-term stability.

How does 4FPEAI reconcile high solubility in polar organic solvents with its hydrophobic moisture barrier functionality?

The molecular structure of 4FPEAI balances these properties through the polar ammonium group ensuring solubility and the fluorine-substituted aromatic ring providing hydrophobicity. The product is freely soluble in DMF and DMSO, while the para-fluorine substituent establishes a strong molecular dipole field and a hydrophobic barrier that repels moisture, enabling defect passivation without sacrificing processability.

What are the essential environmental controls required when using 4FPEAI for perovskite thin-film fabrication?

4FPEAI is strongly hygroscopic and light-sensitive, requiring that all weighing and solution preparation be performed in a nitrogen-filled glovebox with H₂O < 1 ppm and O₂ < 1 ppm. The powder must be transferred immediately from its light-protective packaging to a desiccated, light-protected environment, and containers must be tightly sealed after each use to prevent moisture ingress that would irreversibly degrade precursor stoichiometry.

What long-term storage infrastructure is necessary to maintain the integrity of 4FPEAI?

For long-term storage, an inert-atmosphere glovebox is recommended, with the material stored in a light-protected, moisture-free environment at room temperature. Exposure to atmospheric moisture causes deliquescence and hydrolysis, so the container must be sealed under inert atmosphere and protected from light to prevent photodegradation. Immediate transfer to a desiccated environment after opening is essential.

This 4-fluoro-phenethylammonium iodide precursor provides effective defect passivation and moisture stability for 2D perovskite devices, but its strong hygroscopicity and light sensitivity mandate rigorous inert atmosphere handling and storage.
