Abstract

This study investigates the gate-opening closed-to-open-pore structural transition of a porous coordination polymer induced by CO₂ adsorption. Solid-state ¹³C NMR examination of adsorbed CO₂ and framework dynamics reveals the surface adsorption state of the closed structure below the transition pressure and an intermediate structure during the transition process.
