Due to their network flexibility, metal-org. frameworks (MOFs) may respond to external stimuli such as guest mols., heat, pressure, humidity and so on by a dynamical transformation of their structure. The authors present exptl. studies by nitrogen and argon physisorption at cryogenic temp. concerning the influence of handling and storage on the recently synthesized highly flexible copper-based MOF ∞3[Cu4(μ4-O)(μ2-OH)2(Me2trzpba)4]. Unusual adsorption isotherms with up to three distinct steps in the adsorbed vol. were found substantiating once more: (i) the high sensitivity of flexible network structures for environmental influences, (ii) the high diversity of physisorption isotherm types for flexible materials including isotherms with several steps and large hysteresis loops, and last but not least (iii) that theor. methods assuming inert solids cannot be applied to highly flexible materials for calcg. pore sizes and other solid state parameters.
