Synthesis and X-ray crystal structure of 1-M. a Synthesis of the isostructural series of 1-M from H3 L and different metal ions (only the coordinated oxygen atoms were shown for OAc anions in 1-M(III) and 1-M(IV). Green, M; gold, P; red, O; blue, C). b The 3D hydrophobic structure of 1-M along the c-axis (the metal ions are shown in polyhedral). c A portion of the 3D structure highlighting the exposure of the SBUs to the pores
