Abstract

Unter Druck: Die erste kristallographische Untersuchung des Metall-organischen Gerüsts MOF-5 unter hohem Druck ergab als erste Folge der Druckzunahme, dass das druckübertragende Fluid in die Poren gepresst wird. Bei weiterer Druckerhöhung nahm der Poreninhalt erheblich ab, weil Lösungsmittel aus den Poren austrat, und bei Drücken oberhalb von 3.2 GPa ging schließlich die Kristallinität vollständig verloren.
