Description

GUANIDINIUM IODIDE CH₆IN₃ 99.5% CAS 19227-70-4

RESEARCH GRADE MATERIAL

Product Overview
Guanidinium Iodide (CH₆IN₃, CAS 19227-70-4) is a guanidine-based iodide salt perovskite modification precursor with CH₆IN₃ 99.5% purity, supplied as a white solid with a molecular weight of 186.98 g/mol. This compound functions as an effective perovskite defect passivation additive, where the guanidinium cation features a unique multi-amino hydrogen-bonding structure that effectively regulates crystal growth when incorporated into perovskite thin films. The guanidinium ion’s three amino groups form extensive hydrogen-bonding networks within the perovskite lattice, passivating internal defects, enhancing charge carrier mobility, and significantly improving device thermal stability. Primarily employed in the research preparation of stabilized hybrid perovskite solar cells, photodetectors, and light-emitting devices, this precursor is compatible with solution spin-coating and precursor co-blending experimental processes. With low impurity content and stable batch-to-batch performance, the product requires strict light-sensitive hygroscopic dry storage to maintain material integrity.

Key Features & Advantages
  • Multi-Amino Hydrogen-Bonding Network for Defect Passivation: The guanidinium cation contains three amino groups capable of forming extensive hydrogen-bonding networks within the perovskite lattice, providing superior internal defect passivation compared to single-ammonium cations and significantly reducing non-radiative recombination centers.
  • Enhanced Thermal Stability via Structural Stabilization: The strong hydrogen-bonding interactions between guanidinium ions and the inorganic perovskite framework stabilize the crystal structure against thermal degradation, enabling improved device operational stability at elevated temperatures.
  • Carrier Mobility Enhancement through Defect Reduction: By effectively passivating internal defects that act as charge trapping sites, guanidinium incorporation directly improves charge carrier mobility within the perovskite active layer, contributing to enhanced photovoltaic and optoelectronic device performance.
  • Stable Batch-to-Batch Performance: With >99.5% purity and low impurity content, the precursor delivers consistent experimental results across multiple production batches, supporting reproducible research outcomes in long-term device optimization studies.

APPLICATION SCOPE: Defect passivation additive for stabilized hybrid perovskite solar cells. Crystal growth modulator for improving perovskite thin film morphology and reducing internal defects. Thermal stability enhancement precursor through guanidinium hydrogen-bonding network formation. Carrier mobility improvement agent for perovskite photodetectors and light-emitting devices. Compatible with solution spin-coating and precursor co-blending deposition protocols. Supports research on stable perovskite optoelectronic devices in university and research institute laboratories where thermal stability and defect reduction are experimental priorities.
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 strongly hygroscopic nature of guanidinium 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: Guanidinium iodide is strongly 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 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.
