Selective extraction of uranium from water has attracted worldwide attention because the largest source is seawater with various interference ions (Na+ , K+ Mg2+ Ca2+ etc.). However, traditional adsorbents encapsulate most their functional sites in dense structure, leading to problems low selectivity and adsorption capacities. In this work, tailor-made binding are first decorated into porous skeletons, a series molecularly imprinted aromatic frameworks prepared for extraction. Because architecture provides numerous accessible sites, resultant material fourfold increased ion capacity compared polymers presents highest among all reported adsorbents. Moreover, framework can be dispersed commercial form composite components practical simulated seawater.
