4-METHOXY-PHENETHYLAMMONIUM IODIDE C₉H₁₄INO 99% 4-MEO-PEAI

RESEARCH GRADE MATERIAL

Product Overview

4-Methoxy-Phenethylammonium Iodide (C₉H₁₄INO, 4-MeO-PEAI, Product No. MS100750) is a methoxy-modified phenethyl organic iodide salt precursor with C₉H₁₄INO 99% purity 4-MeO-PEAI, supplied as a white solid with a molecular weight of 279.12 g/mol. This compound functions as an advanced 2D perovskite dipole passivation agent, employed for both 2D and quasi-2D perovskite thin film fabrication and 3D perovskite surface defect passivation. The para-methoxy substituent on the aromatic ring modulates the molecular dipole moment, optimizes perovskite crystallization morphology, fills iodine vacancy defects within the film, and reduces non-radiative recombination losses. The organic alkyl chain simultaneously forms a hydrophobic protective layer that significantly enhances both moisture resistance and thermal stability of perovskite devices. The material is utilized in university and research institute laboratories for two-dimensional perovskite solar cell, photodetector, and perovskite light-emitting diode research. Freely soluble in polar organic solvents including DMF and DMSO, this high-purity precursor is compatible with spin-coating and precursor solution blending thin-film preparation techniques. Strict light-sensitive hygroscopic glovebox storage is required to maintain material integrity.

Key Features & Advantages

Methoxy-Functionalized Dipole Moment Modulation: The electron-donating methoxy substituent on the aromatic ring modulates the molecular dipole moment, providing an additional electronic tuning parameter for optimizing charge transfer dynamics and energy level alignment at perovskite interfaces.
Iodine Vacancy Defect Filling for Reduced Recombination: The iodide counterion directly participates in filling iodine vacancy defects within the perovskite lattice, reducing one of the primary sources of non-radiative recombination centers and extending carrier lifetime in passivated films.
Dual-Function Versatility: 2D Spacer and 3D Passivation: 4-MeO-PEAI 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.
Enhanced Moisture and Thermal Stability: The methoxy-substituted aromatic ring combined with the hydrophobic alkyl chain provides a robust protective barrier that significantly improves both humidity resistance and thermal endurance of completed perovskite devices.

APPLICATION SCOPE: Methoxy-functionalized organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Surface defect passivation agent for 3D perovskite thin films with iodine vacancy filling capability. Crystallization morphology optimization precursor through dipole-modulated intermolecular interactions. Moisture and thermal stability enhancement additive for perovskite optoelectronic devices. Compatible with spin-coating and precursor solution blending deposition protocols. Supports two-dimensional perovskite solar cell, photodetector, and perovskite 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 4-methoxy-phenethylammonium iodide necessitates immediate transfer to a desiccated, light-protected storage environment—preferably a nitrogen-filled glovebox for long-term storage. For bulk quantities or custom packaging specifications, please contact us via email.

IMPORTANT NOTICE: 4-Methoxy-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; avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic 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. This product does not have an assigned CAS number; refer to product number MS100750 for ordering and documentation purposes. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
