This work shows that hollow microporous organic polymer (H‐MOP‐A) with activated internal alkynes as IR probes can be prepared by template synthesis based on acyl Sonogashira‐Hagihara coupling at room temperature. The H‐MOP‐A is a versatile platform in the main chain PSM based on nonradical thiol‐yne click reaction. Moreover, an IR peak of internal alkynes in the H‐MOP‐A is very intense and could be utilized in the monitoring of thiol‐yne click‐based main chain PSM. The functionalized H‐MOP‐A with carboxylic acids (H‐MOP‐CA) showed efficient adsorption toward Ag + ions. The resultant H‐MOP‐CA‐Ag showed excellent performance in the CO 2 fixation to α‐alkylidene cyclic compounds.
