Crystal structure of a JNM-100 and b JNM-100-AO showing space-filling model (C, light pink; H, white; Ag, silver; N, sky blue; O, red). c FT-IR spectra of JNM-100-AO, JNM-100, 1, and Ag3L3. d Solid-state 13C CP-MAS NMR spectra (100 MHz, 300 K) of JNM-100-AO, and JNM-100, and 13C NMR (100 MHz, 300 K, DMSO) spectra of linker 1 (red) and ligand HL (black) (*marked resonances represent spinning sideband). e The stability test of JNM-100-AO in strong acid and base as well as in various solvents. The N2 adsorption (filled) and desorption (open) isotherm profiles of f JNM-100, and g JNM-100-AO at 77 K. (inset the pore-size distribution curves of JNM-100-AO, and JNM-100 showing a uniform pore size of ∼1.96 and 1.65 nm, respectively).
