Products Description
TAPB features a rigid, C3-symmetric triamino structure, making it a classic building block for tri-topic COFs.
Its rigid molecular backbone facilitates the formation of highly crystalline COFs with regular, ordered pore channels.
With abundant active amino sites, it undergoes Schiff-base condensation with various aldehyde monomers, making it compatible with a wide range of COF systems.
The resulting COF materials exhibit high porosity and excellent performance in gas adsorption, catalysis, and separation; they are also suitable for the synthesis of high-performance polyimides and microporous polymers.

3. Intermediate for organic semiconductors and photoelectric materials.
FAQ
Q: What are the key points to keep in mind when preparing polyimide using TAPB besides conducting COF?
A: A three-functional group crosslinkable gel. For film formation, a low proportion of co-inclusion is required; the entire process is oxygen-free and waterproof; it is polymerized at low temperatures; the higher the addition amount, the more brittle the film becomes, and it turns yellow and oxidizes. The raw materials used must not be oxidized.
Q: When TAPB synthesizes COF, what are the main reasons for the low crystallinity of the product?
A: Raw materials oxidized and deteriorated; inappropriate solvent system / ratio; insufficient reaction temperature and time; imbalance in monomer molar ratio; inadequate oxygen removal.
Q: What impact will the deviation in the mole ratio of the feedstock for TAPB have on the pore structure of COF?
A: Excessive monomers will lead to structural defects, a wider pore size distribution, a decrease in specific surface area, and a deterioration in the regularity of the pore channels.
Q: How to store?
A: Store at 2-8°C in a nitrogen-sealed container. Protect from light and keep away from air to prevent moisture. Do not open the container repeatedly as exposure to oxygen may cause oxidation and deterioration.
