Metal-organic frameworks (MOFs) constructed with cavity-containing inherently porous organic cage linkers are rare. Among these, none have provided structural evidence of guest molecules being hosted inside the linkers. Such materials highly desirable for trapping carcinogenic polycyclic aromatic hydrocarbons (PAHs) from water, which remains challenging existing adsorbents. Herein, we present first example a metal-“organic cage” framework encapsulated within MOF. We utilize triazole-equipped click (CC-1) and Ag(I)-triazole coordination to generate dual-porous, water-stable, spontaneously resolved, chiral MOF (MOF-CC-1) in srs topology. MOF-CC-1 encapsulates diverse range PAHs cavity CC-1, as confirmed structurally. Additionally, demonstrates excellent adsorption capacity water. This study offers promising strategy developing efficient adsorbents remove
