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.

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

The electron-withdrawing chlorine substituent 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. This chloro-substituted cation influences crystallization kinetics through modified intermolecular interactions, promoting improved film morphology with reduced defect density compared to unsubstituted PEAI, while the chlorine-substituted aromatic tail provides a hydrophobic moisture barrier for combined electronic passivation and environmental protection.

What are the critical handling requirements for 4-chloro-phenethylammonium iodide during precursor solution preparation?

The white solid powder must be handled within an inert-atmosphere glovebox with H₂O < 1 ppm and O₂ < 1 ppm to prevent deliquescence and hydrolysis, as exposure to atmospheric moisture irreversibly degrades precursor stoichiometry. The compound is hygroscopic and light-sensitive, requiring immediate transfer to a desiccated, light-protected environment upon receipt. It is compatible with spin-coating and precursor solution blending deposition protocols for 2D perovskite thin-film preparation.

What storage conditions are required to maintain the integrity of 4-chloro-phenethylammonium iodide?

Store in a light-protected, moisture-free, sealed container at room temperature. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Do not store together with strong oxidizing agents or acidic reagents. The material is supplied under inert atmosphere within light-protective packaging; upon receipt, transfer to a desiccated, light-protected environment to prevent photodegradation and moisture ingress.

4-Chloro-Phenethylammonium Iodide (99%) is a chlorine-substituted organic spacer cation for 2D perovskite synthesis, offering dipole modulation via the electron-withdrawing chloro group and dual-function passivation with a hydrophobic moisture barrier. Its high purity supports reproducible device fabrication, but the material's hygroscopic and light-sensitive nature mandates inert-atmosphere glovebox handling and strict light-protected, dry storage to prevent degradation.
