Description

DIMETHYLAMMONIUM IODIDE C₂H₈IN 99% DMAI CAS 51066-74-1

RESEARCH GRADE MATERIAL

Product Overview

Dimethylammonium Iodide (C₂H₈IN, DMAI, CAS 51066-74-1) is a small-molecule alkyl iodide salt perovskite precursor with C₂H₈IN 99% purity DMAI, supplied as a white solid powder with a molecular weight of 173.99 g/mol and freely soluble in polar solvents including DMF, DMSO, and methanol. This compound functions as an effective perovskite lattice distortion modulator, where the compact dimethylammonium cation is commonly employed for doping modification of three-dimensional perovskites and the preparation of low-dimensional and two-dimensional perovskite materials. The secondary ammonium cation regulates perovskite lattice distortion, optimizes grain size, passivates iodine vacancy defects, and reduces non-radiative recombination losses, thereby enhancing charge carrier mobility and device thermal stability. Compatible with perovskite solar cell, photodetector, and light-emitting diode research applications, this precursor supports spin-coating and precursor co-blending preparation techniques. With stable batch-to-batch purity and low impurity content, the product requires strict light-sensitive hygroscopic glovebox storage to maintain material integrity.

Key Features & Advantages

  • Compact Secondary Ammonium for Lattice Distortion Engineering: The small dimethylammonium cation introduces controlled lattice distortion in 3D perovskite structures, providing a steric tuning parameter distinct from monovalent primary ammonium cations for modulating crystal symmetry and optoelectronic properties.
  • Iodine Vacancy Passivation via Secondary Ammonium Chemistry: The dimethylammonium cation effectively stabilizes the local chemical environment around iodine sites, passivating halide vacancy defects that are primary contributors to non-radiative recombination losses in perovskite thin films.
  • Versatile Application from 3D Doping to Low-Dimensional Perovskites: DMAI serves both as a doping modifier for three-dimensional perovskite compositions and as a precursor for low-dimensional and 2D perovskite material synthesis, providing broad experimental utility across multiple perovskite research domains.
  • Excellent Polar Solvent Solubility for Processing Flexibility: Freely soluble in DMF, DMSO, methanol, and other polar solvents, the precursor integrates seamlessly into standard perovskite deposition workflows without requiring specialized solvent systems.

APPLICATION SCOPE: Doping modifier for three-dimensional perovskite lattice distortion engineering and grain size optimization. Precursor for low-dimensional and two-dimensional perovskite material synthesis. Iodine vacancy passivation agent for reducing non-radiative recombination in perovskite thin films. Carrier mobility and thermal stability enhancement additive for perovskite solar cells. 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 dimethylammonium 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: Dimethylammonium 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. 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.

Dimethylammonium iodide is highly hygroscopic and light-sensitive, requiring storage under inert atmosphere with moisture and light protection. Exposure to ambient moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.

  • Moisture Sensitivity: The compound undergoes deliquescence and hydrolysis upon exposure to atmospheric moisture, irreversibly altering its chemical composition.
  • Light Sensitivity: Prolonged exposure to light degrades the material, necessitating light-protective packaging and storage.
  • Inert Atmosphere Requirement: Powder weighing and solution preparation must be performed in a nitrogen-filled glovebox with H2O < 1 ppm and O2 < 1 ppm to prevent degradation.
  • Solvent Compatibility: The precursor is freely soluble in polar solvents such as DMF, DMSO, and methanol, and should be formulated using these solvents.
  • Container Integrity: The container must be tightly sealed immediately after each use to prevent moisture ingress from ambient air.

Dimethylammonium iodide is a hygroscopic, light-sensitive perovskite precursor that requires inert-atmosphere handling. Proper storage and preparation are critical to maintain material integrity and experimental reproducibility.

Required Equipment: Nitrogen Glovebox, Desiccator, Light-Protective Container, Weighing Scale

  1. Inspect and Transfer
    Inspect the received package for damage and transfer immediately to a light-protected, desiccated storage environment.
  2. Set Up Glovebox
    Place all necessary equipment and the compound container inside a nitrogen-filled glovebox prior to opening.
  3. Weigh Under Inert Atmosphere
    Weigh the required amount of dimethylammonium iodide under inert atmosphere using a clean spatula and weigh boat.
  4. Dissolve in Solvent
    Dissolve the weighed powder in anhydrous dimethylformamide, dimethyl sulfoxide, or methanol to prepare the precursor solution.
  5. Reseal and Store
    Tighten the container cap immediately after use and return the material to inert atmosphere storage.

How does dimethylammonium iodide doping affect the trade-off between lattice distortion and charge carrier mobility in perovskite thin films?

DMAI introduces controlled lattice distortion via its compact secondary ammonium cation, which optimizes grain size and passivates iodine vacancy defects. This reduces non-radiative recombination losses while enhancing charge carrier mobility and thermal stability, providing a steric tuning parameter distinct from primary ammonium cations without sacrificing mobility.

What are the critical solvent compatibility requirements for using DMAI in perovskite precursor solutions?

DMAI is freely soluble in polar solvents such as DMF, DMSO, and methanol, integrating seamlessly into standard spin-coating and precursor co-blending workflows without requiring specialized solvent systems. However, due to its hygroscopic nature, all solution preparation must be performed in a nitrogen-filled glovebox with H₂O < 1 ppm and O₂ < 1 ppm to prevent moisture-induced degradation.

What specific storage infrastructure is required to prevent degradation of dimethylammonium iodide?

DMAI must be stored in a light-protected, dry, sealed container at room temperature; long-term storage requires a nitrogen-filled glovebox with H₂O < 1 ppm and O₂ < 1 ppm. It is hygroscopic and light-sensitive—exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Immediate transfer to a desiccated, light-protected environment after opening is essential.

Dimethylammonium Iodide (DMAI) is a perovskite precursor with 99% purity that enables lattice distortion engineering and iodine vacancy passivation, but requires strict inert-atmosphere handling due to hygroscopic and light-sensitive properties.
