Breathtaking MOFs: DFT calculations reveal that the exceptional, thermally induced density change of the metal-organic framework MIL53(Al) is controlled by a competition between shortand long-range interactions and entropic factors. As shown in the picture (C green, Al cyan, O red, H white), dispersive interactions between the phenyl rings are responsible for stabilizing a narrow-pore form at low temperature. At 325-375 K, vibrational entropy causes the structure to expand markedly, permitting large volumes of light gases to be adsorbed. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
