摘　　要：The adsorption method is considered to be one of the most promising organic pollutants emission reduction strategies.The design and synthesis of high-performance porous adsorbents are one of the most important but challenging works.In this work,we constructed a new class of porous molecular cage switches by a simple reaction using phenolphthalein as the raw material.The molecular cage switches displayed interesting on-off behavior towards organic guests,which is highly responding to organic pollutants with rapid color change and is also able to adsorb these organic pollutants through an open-to-close pathway.This molecular cage switch also has excellent regenerative cycling properties and water resistance,which is expected to be employed in the handling of organic pollutants in the future.
