摘要
(Graph Presented) Open the gate! A porous coordination polymer shows abrupt changes in its adsorption isotherm with guest-dependent gate-opening pressure (see picture). Kinetic analysis reveals that adsorption with structure transformation follows a gate-opening model, in which adsorption proceeds through the formation of an intermediate by a gate-opening process. This process provides a significant difference in onset pressure between similar gas molecules. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
