PHENETHYLAMMONIUM CHLORIDE C₈H₁₂CLN 99% PEACL CAS 156-28-5

RESEARCH GRADE MATERIAL

Product Overview

Phenethylammonium Chloride (C₈H₁₂ClN, PEACl, CAS 156-28-5) is a classic organic chloride salt precursor for 2D perovskite research with C₈H₁₂ClN 99% purity PEACl, supplied as a white solid powder with a molecular weight of 157.64 g/mol. This compound functions as a versatile 2D perovskite surface passivation agent, employed both for fabricating 2D and quasi-2D perovskite thin films and as a surface passivation additive for modifying 3D perovskite surfaces. The phenethyl long organic chain forms a hydrophobic protective layer that blocks moisture ingress, reduces thin film surface defect density, and suppresses non-radiative recombination, thereby enhancing both the environmental stability and power conversion efficiency of perovskite optoelectronic devices. The chloride ion simultaneously regulates crystal growth and optimizes grain morphology during film formation. Freely soluble in polar organic solvents including DMF and DMSO, this precursor is compatible with spin-coating and precursor co-blending preparation techniques for perovskite solar cell, photodetector, and light-emitting diode research. The product requires strict light-sensitive hygroscopic glovebox storage to maintain material integrity.

Key Features & Advantages

Dual-Function Versatility: 2D Spacer and 3D Surface Passivation: PEACl serves simultaneously as the organic spacer cation for 2D/quasi-2D perovskite fabrication and as a surface passivation additive for 3D perovskite films, providing experimental flexibility across multiple device architectures from a single precursor material.
Hydrophobic Protective Layer with Chloride Morphology Control: The phenethyl organic chain forms a moisture-blocking hydrophobic barrier while the chloride ion regulates crystal growth kinetics, delivering combined environmental protection and optimized grain morphology in a single treatment step.
Surface Defect Density Reduction for Enhanced Efficiency: Ammonium head group passivation of surface defect states reduces non-radiative recombination losses, directly contributing to improved open-circuit voltage and overall power conversion efficiency in completed perovskite solar cells.
Excellent Polar Solvent Solubility for Processing Flexibility: Freely soluble in DMF, DMSO, and other polar organic solvents, the precursor integrates seamlessly into standard perovskite deposition workflows without requiring specialized solvent systems or processing modifications.

APPLICATION SCOPE: Classic organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Surface passivation additive for modifying and stabilizing 3D perovskite thin film surfaces. Hydrophobic barrier precursor for moisture-resistant perovskite optoelectronic devices. Crystal growth modulator with chloride-mediated grain morphology optimization. Compatible with spin-coating and precursor co-blending deposition protocols. Supports perovskite solar cell, photodetector, and light-emitting diode 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 phenethylammonium chloride 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: Phenethylammonium chloride 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 alkaline 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.
