Description
C70 Malonic Ester (SOL5373) – High-Performance Methanofullerene & Electrolyte Additive
C70 malonic ester (SOL5373), or C70-n-(malonic ester), is a high-performance methanofullerene derivative specifically engineered as an n-type semiconductor, electron transport layer (ETL) material, and battery electrolyte additive. Manufactured by Solaris Chem, SOL5373 features a high degree of functionalization that delivers superior solubility in dimethyl carbonate (DMC) and a broader visible light absorption spectrum compared to standard C60 fullerenes.
Key Advantages of C70 Malonic Ester vs. C60 Derivatives
- Broader Absorption Spectrum: Its asymmetrical, rugby-ball shape allows C70 to absorb significantly more light across the visible spectrum, increasing short-circuit current in solar cell devices.
- Enhanced Carbonate Solubility: Malonic ester functionalization (n ≥ 3) dramatically increases solubility in polar and carbonate solvents like dimethyl carbonate (DMC).
- Optimized Energy Levels: Precise HOMO/LUMO energetic alignment tailored for seamless integration with modern donor polymers and perovskite crystal structures.
Primary Industrial & R&D Applications
1. Advanced Battery Electrolytes
SOL5373 acts as a high-efficiency additive for lithium-ion battery electrolytes. It promotes solid electrolyte interphase (SEI) stabilization to protect electrodes from degradation and serves as a radical scavenger to enhance battery thermal safety.
2. Organic Photovoltaics (OPV) & Perovskite Solar Cells
Functions as an exceptional electron transport layer (ETL) material. High electron mobility and film-forming capability enable thinner, highly efficient device architectures, particularly in inverted perovskite solar cell configurations.
Storage and Handling for Optimal Performance
- Inert Atmosphere: Store under Argon or Nitrogen atmosphere to prevent photo-oxidation.
- Light Protection: Keep in amber glass vials or light-shielded containers.
- Temperature Control: Store in a cool, dry environment (preferably < 25°C).
