Analog Structure  
Product Property
Appearance    
Particle Size About 1.8 ± 0.2 nm
Stability
1) COF-I is susceptible to damage under changes in pH, temperature, and humidity, indicating poor stability of its structure under external environmental changes.
2) By adjusting the pH value and reaction time, COF-I can achieve reconstruction from disorder to order, demonstrating a certain regenerative ability.
Preservation
1) Dry and sealed under normal temperature or low temperature conditions 
2)  Before use, its porous structure can be restored by appropriate solvent treatment and pH adjustment.
Other Features
Fluorescence:NA
Applications
1) Due to its high specific surface area and adjustable pore structure, COF-I may be suitable for gas adsorption and separation fields.
2) Its reconstruction capability indicates that COF-I may have a longer service life in practical applications, especially in environments that require structural stability and renewability.
