A pore-free adsorbent with abundant active sites is beneficial for the fast separation of uranium. The two-dimensional olefin-linked conjugated organic polymer prepared in this study showed good stability, excellent fluorescence property, and high N atom content, resulting in excellent performance in uranium adsorption and separation. Its nearly pore-free structure, due to irregular staggered stacking, exhibited fast adsorption behavior towards uranium, confirming the feasibility of pore-free materials for rapid adsorption.
Design and preparation of a kind of pore-free adsorbent with abundant active sites is favorable for fast separation of uranium. Here, a two-dimensional olefin-linked conjugated organic polymer was prepared via the Knoevenagel condensation reaction. The product owns good stability and excellent fluorescence property due to the fully conjugated skeleton. Moreover, owning to the high content of N atom, it shows excellent performance in adsorption and separation of uranium, and more importantly, it is constructed with nearly pore-free structure because of the irregular staggered stacking, which makes it exhibit fast adsorption behavior towards uranium. These results confirm the feasibility of pore-free material for fast adsorption.
