Description

4-FLUORO-PHENETHYLAMMONIUM BROMIDE C₈H₁₁BRFN 99% 4FPEABR CAS 1807536-06-6

RESEARCH GRADE MATERIAL

Product Overview
4-Fluoro-Phenethylammonium Bromide (C₈H₁₁BrFN, 4FPEABr, CAS 1807536-06-6) is a para-fluorine modified phenethyl organic bromide salt precursor with C₈H₁₁BrFN 99% purity 4FPEABr, supplied as a white powder with a molecular weight of 220.08 g/mol and freely soluble in perovskite-relevant polar organic solvents including DMF and DMSO. This compound functions as an advanced 2D perovskite defect passivation agent, employed for both 2D and quasi-2D bromide-based perovskite thin film fabrication and as a surface passivation additive for 3D perovskite films. The para-fluorine substituent on the aromatic ring modulates molecular dipole moment, optimizes crystal growth orientation, and passivates grain boundary and surface defects, thereby reducing non-radiative recombination. The fluorine-substituted alkyl chain provides strong hydrophobic characteristics that block moisture penetration, significantly enhancing the environmental stability of bromide-based perovskite light-emitting devices and photodetectors. Extensively purified with stable batch-to-batch experimental reproducibility, this precursor is compatible with spin-coating and precursor co-blending preparation techniques. Widely utilized in university and research institute laboratories for narrow-bandgap light emission, X-ray detection, and two-dimensional photovoltaic research, the product requires strict light-sensitive hygroscopic glovebox storage to maintain material integrity.

Key Features & Advantages
  • Fluorine-Modulated Dipole for Crystal Orientation Control: The electron-withdrawing para-fluorine substituent establishes a molecular dipole that influences crystal growth orientation during perovskite film formation, promoting favorable grain alignment for enhanced charge transport in bromide-based devices.
  • Bromide Analog for Halide Consistency in Passivation: As the bromide salt variant in the fluoro-phenethylammonium series, 4FPEABr provides halide-matched passivation for bromide-based perovskite compositions, eliminating halide exchange effects that can alter bandgap during surface treatment.
  • Strong Hydrophobic Barrier with Defect Passivation: The fluorine-substituted aromatic ring provides enhanced hydrophobicity compared to unsubstituted PEABr, delivering superior moisture protection while the ammonium head group simultaneously passivates grain boundary and surface defect states.
  • Stable Batch-to-Batch Reproducibility: Extensively purified with >99% purity and rigorous quality control, the precursor ensures consistent experimental data reproducibility and reliable device performance across extended research programs.

APPLICATION SCOPE: Fluorine-functionalized organic spacer cation for 2D and quasi-2D bromide-based perovskite synthesis. Halide-matched surface passivation agent for bromide perovskite thin films. Crystal growth orientation optimization precursor via dipole-modulated nucleation. Hydrophobic barrier additive for moisture-resistant perovskite light-emitting devices and photodetectors. Compatible with spin-coating and precursor co-blending deposition protocols. Supports narrow-bandgap light emission, X-ray detection, and two-dimensional photovoltaic research in university and research institute laboratories.
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 bromide necessitates immediate transfer to a desiccated, light-protected storage environment—preferably a nitrogen-filled glovebox for long-term storage. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: 4-Fluoro-Phenethylammonium bromide is 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 inert 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.
