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.

Key Features & Advantages

Fluorine-Functionalized Surface Energy Modulation: 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 for optimizing device energy level alignment and charge extraction efficiency.
Combined Electronic and Structural Passivation: 4FPEACl simultaneously passivates grain boundary defects through the ammonium head group while the fluorine-substituted aromatic tail modulates local electronic environment, delivering synergistic passivation effects that enhance both stability and optoelectronic performance.
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.
