摘要

Selective recognition and dense packing of SO2 clusters is achieved through multiple synergistic host-guest/guest-guest interactions within SiF62- anion-pillared hybrid porous materials in article number1606929, by Qiwei Yang, Banglin Chen, Huabin Xing, and co-workers. The binding sites of anions and aromatic rings on the pore surface grasp every atom of SO2 via Sδ+⋯Fδ– and Oδ–⋯Hδ+interactions, while the interactions between SO2 molecules further promote the gas trapping.
