Fig. 1: Crystal structure and origami tessellation unveiled in PPF-301.
From: Origamic metal-organic framework toward mechanical metamaterial
A Two building blocks for PPF-301: Zn2(COO)4 SBU and TCMOPP linker. Zn = yellow; C = gray; N = blue; O = red; all hydrogen atoms and solvent molecules are omitted for clarity. B Simplification of 2D porphyrinic MOF, leading to origami tessellation. Solvents and hydrogen are omitted for clarity. The blue and yellow tiles filled the TCMOPP linker and Zn SBU, respectively. Red balls are oxygen atoms of the aryloxy group.
