1,3,6,8-Tetrabromopyrene, Branched polyethyleneimine, Fluorescence spectra, Gravimetric yield, Water-soluble


In this thesis, we report a novel covalent organic framework (COF) with fluorescence and water-soluble features, F-COF-PT with high gravimetric yield (~ 89%), that was generated by the reactions of branched polyethyleneimine (PEI) and 1,3,6,8-Tetrabromopyrene (TBP). The surface area and pore volume were about up to 63.2 m2/g and 0.41 m3/g. The prepared COFs maintained the TBP fluorescent performance in water solutions at 440-460 nm. Furthermore, Cu(II) ion solution would impact the quenching activity with F-COF-PT3, and NaOH treated F-COF-PT3 has the 5.6 m2/g capacity of uptake CO2. Finally, the zeta potential and particle diameter of original and treated F-COF-PT3s were measured to evaluate the stability of the prepared COF solutions and the particle size in the water solutions.
