Stability

1) TFPB-DHBD-COF remains stable when soaked in water, N,N-dimethylformamide, tetrahydrofuran, toluene, 1.0 M HCl, and 1.0 M NaOH aqueous solutions at room temperature for 5 days;

Preservation

1) Store in a dry and cool place, sealed.

2) It is recommended to activate in a vacuum oven at room temperature for 3 hours before use.

Other Features

1) Fluorescence: DhBd-PT-COF-FITC is fluorescent, with an excitation wavelength λex = 490 nm and an emission wavelength λem = 520 nm. 2) TFPB-DHBD-COF is rich in hydroxyl groups, which can activate epoxides and carbon dioxide through hydrogen bonds, and the intramolecular five-membered ring hydrogen bond enhances its stability.

Applications

1) Catalysis: Efficiently catalyze the cycloaddition of carbon dioxide and epoxides to prepare cyclic carbonates. 2) Detection: Used to detect 3-nitropropionic acid in moldy sugarcane, with a detection limit as low as 12.5 nM.
