PHENETHYLAMMONIUM BROMIDE C₈H₁₂BRN 99% PEABR CAS 53916-94-2

RESEARCH GRADE MATERIAL

Product Overview

Phenethylammonium Bromide (C₈H₁₂BrN, PEABr, CAS 53916-94-2) is a specialized organic bromide salt with C₈H₁₂BrN 99% purity PEABr, supplied as a white crystalline solid with a molecular weight of 202.09 g/mol. This compound functions as a critical 2D perovskite passivation layer precursor, employed to modulate perovskite thin film dimensionality and passivate surface defect states. By introducing the phenethylammonium spacer cation, researchers can effectively suppress non-radiative recombination at grain boundaries and interfaces, significantly enhancing both the stability and power conversion efficiency of perovskite solar cells. The material is widely utilized in university and research institute laboratories for photovoltaic device, photodetector, and light-emitting diode experimental research. Compatible with mainstream thin-film processing techniques including spin-coating and solution blending, this high-purity precursor delivers consistent passivation performance. Strict light-sensitive hygroscopic dry storage is required to maintain material integrity.

Key Features & Advantages

Effective Surface Defect Passivation: The phenethylammonium cation selectively passivates surface and grain boundary defect states in 3D perovskite films, suppressing non-radiative recombination pathways and directly contributing to enhanced open-circuit voltage and fill factor in completed photovoltaic devices.
Dimensionality Engineering for Improved Stability: PEABr serves as the spacer cation for 2D Ruddlesden-Popper phase perovskite formation, where the aromatic phenethyl group provides superior moisture resistance compared to aliphatic ammonium counterparts, significantly extending device operational lifetime.
Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects introduced during passivation layer deposition, ensuring reproducible device performance across experimental batches.
Room Temperature Storage Convenience: The material is stored at room temperature under light-protected, dry, sealed conditions, simplifying laboratory inventory management without requiring refrigeration or freezing equipment.

APPLICATION SCOPE: Specialized organic spacer cation for 2D Ruddlesden-Popper phase perovskite synthesis. Surface passivation agent for 3D perovskite thin films in high-efficiency solar cells. Precursor for 2D/3D mixed-dimensional perovskite heterostructures combining high efficiency with improved environmental stability. Compatible with spin-coating and solution blending deposition protocols. Supports perovskite light-emitting diode, photodetector, and other optoelectronic device research requiring reduced non-radiative recombination losses. Widely adopted in university and research institute laboratories for photovoltaic device stability enhancement studies.

PACKAGING: This listing is for the 10 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 bromide 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: 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 to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white crystalline solid within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For detailed safety and handling information, consult the Safety Data Sheet prior to use.
