摘要：

The big squeeze: On applying pressure to ZIF-8 (0.18 GPa), solvent can be squeezed into the porous cavities, initially increasing the pore size and unit-cell volume. On increasing pressure further to 1.47 GPa, a phase transition takes place (see picture). This transition allows more solvent to enter the original nanopores and enlarges the narrow channels connecting these pores, resulting in higher porous volume and solvent content. © 2009 Wiley-VCH Verlag GmbH & Co.
