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.
