Figure Lengend Snippet: a) UV–Vis absorption spectra obtained from diffuse reflectance spectroscopy of the solid MOF; the background spectra represent the UV–Vis spectra acquired in the DMF solution of the respective M‐TCPP linker. b) N 2 adsorption–desorption isotherms of the MOFs. c) Pore size distribution curves. Representation of two types of cavities, d) cubic (top) and e) octahedral (bottom), interconnected to form open channels in three dimensions of PCN 221 MOF. The structure depicted here was obtained from CCDC 925 058 [ ³⁷ ] and was analyzed, and visualized using Dimond and Vesta software, respectively for enhanced clarity and precision.

Article Snippet: Steady‐state UV–Vis absorption spectroscopy was performed on a V‐760 JASCO UV–VIS‐NIR Spectrophotometer, and steady‐state emission spectroscopy was performed on a JASCO FP‐8500 Spectrofluorometer.
