Fig. 5: Post-assembly modification of Ti24 MOPs.
From: Hierarchical assembly of a Ti24 metal-organic polyhedron via kinetic trapping of intermediates

a Photographs and schematic of surface ligand exchange on Ti24 MOPs, where acetate ligands (CH3COO–, FIR-151) are replaced by methacrylic acid (CH2=C(CH3)COO–, FIR-154) and benzoic acid (C6H5COO–, FIR-155), scale bar = 50 μm. Crystal packing of modified Ti24 MOPs viewed along the c-axis: b FIR-154, c FIR-151, and d FIR-155. Atom colors: Ti sky blue, C gray, O red. The green dashed lines indicate hydrogen bonds or π-π interactions between adjacent MOPs.
