A quadrangular prismatic tricyclooxacalixarene cage 1 based on tetraphenylethylene (TPE) was efficiently synthesized by a one‐pot S N Ar condensation reaction. As a result of the porous internal structure in the solid state, cage 1 exhibited a good CO 2 uptake capacity of 12.5 wt % and a high selectivity for CO 2 over N 2 adsorption of 80 (273 K, 1 bar) with a BET surface area of 432 m 2 g −1 . Formation of cage 1 led to the fluorescence of TPE being switched on in solution. The system was employed as a single‐molecule platform to study the mechanism of aggregation‐induced emission (AIE) by examining the restriction of intramolecular rotation (RIR).
