文摘

Polymer nanopores have great potential for ultrafiltration, desalination, and energy conversion because of their robustness, flexibility, and efficiency in large-scale production. Yet a challenge in controlling the size to subnanometer limits their performance. F. Liu, Y. Wang, and co-workers describe on page 5796, the generation of negatively charged subnanometer polymer pores that exhibit ultra-high ionic transport selectivity and a unique order as Li⁺>Na⁺>K⁺>Cs⁺≫Mg²⁺>Ca²⁺>Ba²⁺≫blocked heavy metal ions and anions.
