Three-Dimensional Metal−Organic Frameworks Based on Tetrahedral and Square-Planar Building Blocks: Hydrogen Sorption and Dye Uptake Studies

Two three-dimensional metal−organic frameworks (MOFs) with tetraphenylmethane-derived tetracarboxylate linkers and copper paddle-wheel secondary building units were synthesized and characterized by single-crystal X-ray crystallographic studies. The two MOFs show a similar 4,4-connectivity but very different homocrossing and interpenetrating PtS network topologies and exhibit permanent porosity as probed by gas adsorption and dye inclusion experiments.
