Abstract

Abstract : According to in situ Raman experiments, in certain pressure ranges open (op) and closed pore (cp) phases coexist in DUT-8(Ni) crystals. Abstract : Experimental in situ observations of phase coexistence in switchable metal–organic frameworks are reported to provide a fundamental understanding of dynamic adsorbents that can change their pore structure in response to external stimuli. A prototypical flexible pillared layer framework DUT-8(Ni) (DUT = Dresden University of Technology) was studied under hydrostatic pressure by in situ Raman spectroscopy on single crystals. The closing transition of the open pore phase (op) containing DMF in the pores in silicon oil as a pressure transmitting fluid, as well as the closed pore phase (cp) to op transition under pressure in methanol, were studied. Phase coexistences during both transitions were observed.
