Three-dimensional metal-organic frameworks based on tetrahedral and square-planar building blocks: Hydrogen sorption and dye uptake studies

摘要

Two three-dimensional metal-organic frameworks (MOFs) with tetraphenylmethane-derived tetracarboxylate linkers and copper paddlewheel 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.
