Description

4-CHLORO-PHENETHYLAMMONIUM IODIDE 99% CAS 1639014-61-1

RESEARCH GRADE MATERIAL

Product Overview
4-Chloro-Phenethylammonium Iodide (CAS 1639014-61-1) is a chlorine-substituted modified phenethyl organic iodide salt precursor with 99% purity white powder form. This compound functions as an advanced 2D perovskite dipole modulator, where the electron-withdrawing chlorine substituent on the aromatic ring modulates molecular dipole interactions within the perovskite lattice. The chloro-phenethylammonium cation simultaneously passivates grain boundary and surface defects while blocking moisture penetration through the hydrophobic aromatic barrier, significantly enhancing both the environmental stability and power conversion efficiency of perovskite optoelectronic devices. The material is utilized in university and research institute laboratories for two-dimensional perovskite solar cell, photodetector, and light-emitting device experimental research. Compatible with spin-coating and precursor solution blending thin-film preparation techniques, this high-purity precursor requires strict light-sensitive hygroscopic dry storage to maintain material integrity.

Key Features & Advantages
  • Chlorine-Functionalized Dipole Engineering: The electron-withdrawing chlorine substituent on the aromatic ring modulates molecular dipole interactions within the perovskite lattice, providing an additional electronic tuning parameter beyond simple spacer length for optimizing optoelectronic properties in 2D perovskite systems.
  • Enhanced Crystallization Quality via Substituent Effects: The chloro-substituted phenethylammonium cation influences perovskite crystallization kinetics through modified intermolecular interactions, promoting improved film morphology with reduced defect density compared to unsubstituted PEAI.
  • Dual-Function Passivation with Moisture Barrier: 4-Chloro-PEAI simultaneously passivates grain boundary and surface defects through the ammonium head group while the chlorine-substituted aromatic tail provides a hydrophobic moisture barrier, delivering combined electronic passivation and environmental protection.
  • Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in 2D perovskite thin films and supports reproducible device performance across experimental batches.

APPLICATION SCOPE: Chlorine-functionalized organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Crystallization quality optimization agent for perovskite thin films through substituent-modified intermolecular interactions. Surface and grain boundary passivation precursor with combined electronic passivation and moisture barrier functionality. Dipole modulation additive for tuning optoelectronic properties in layered perovskite structures. Compatible with spin-coating and precursor solution blending deposition protocols. Supports two-dimensional perovskite solar cell, photodetector, and light-emitting device 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-chloro-phenethylammonium iodide 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-Chloro-Phenethylammonium iodide 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 solid powder 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.

This material is hygroscopic and light-sensitive, requiring strict protection from moisture and light to prevent deliquescence and hydrolysis. Handling must be performed under inert atmosphere to maintain stoichiometric integrity and avoid irreversible degradation.

  • Storage Conditions: Store in a light-protected, dry, sealed container at room temperature, away from strong oxidizing agents and acidic reagents.
  • Moisture Sensitivity: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading the precursor stoichiometry.
  • Inert Atmosphere Requirement: All handling and preparation must be conducted inside an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm.
  • Light Sensitivity: Photodegradation is prevented by immediate transfer to light-protective packaging upon receipt.

This protocol ensures material integrity during storage and precursor solution preparation. Strict adherence to inert atmosphere and moisture-free conditions is required to prevent degradation.

Required Equipment: Inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm), Light-protective storage container, Protective gloves, Desiccator

  1. Inspect packaging
    Inspect the sealed packaging for any damage or moisture ingress immediately upon receipt.
  2. Transfer to glovebox
    Transfer the entire sealed container into an inert-atmosphere glovebox without opening to ambient air.
  3. Weigh and prepare solution
    Weigh the desired amount of powder and prepare precursor solutions exclusively under inert atmosphere to avoid moisture contamination.
  4. Seal container after use
    Tighten the container cap immediately after each removal of material to prevent moisture ingress from ambient air.
  5. Store properly
    Store the sealed container in a light-protected desiccator at room temperature, away from strong oxidizing agents and acidic reagents.

How does the chlorine substituent on 4-chloro-phenethylammonium iodide affect dipole modulation and device performance compared to unsubstituted PEAI?

The electron-withdrawing chlorine substituent on the aromatic ring provides an additional electronic tuning parameter beyond simple spacer length, modulating molecular dipole interactions within the perovskite lattice. This influences crystallization kinetics through modified intermolecular interactions, promoting improved film morphology with reduced defect density compared to unsubstituted PEAI, as stated in the product description.

Is 4-chloro-phenethylammonium iodide compatible with spin-coating deposition for 2D perovskite solar cells, and what are the critical handling constraints for precursor solution preparation?

Yes, it is compatible with spin-coating and precursor solution blending thin-film preparation techniques. However, due to its hygroscopic and light-sensitive nature, the white solid powder must be handled within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm) when preparing precursor solutions to prevent deliquescence and hydrolysis that irreversibly degrade precursor stoichiometry.

What specific storage conditions are required to prevent degradation of 4-chloro-phenethylammonium iodide after opening?

The material requires strict light-protected, hygroscopic dry storage in a sealed container at room temperature. Immediately after each use, tighten the container cap to prevent moisture ingress from ambient air. Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Do not store together with strong oxidizing agents or acidic reagents.

This 99% purity 4-Chloro-Phenethylammonium Iodide provides a chlorinated spacer cation for 2D perovskite dipole engineering and combined defect passivation and moisture barrier, but demands stringent moisture- and light-free handling and storage to preserve its chemical integrity.
