Dynamic breathing behaviour of the titanium-based metal-organic framework NTU-9 upon adsorption of water and organic solvents.

ABSTRACT: Understanding the structural response of framework materials to external stimuli has been of great interest. However, little is known about the stimuli responsiveness of titanium-based metal-organic frameworks. We investigate the reproducibility of the synthesis of the two-dimensional metal-organic framework NTU-9 (NTU = Nanyang Technological University) composed of Ti⁴⁺ cations and 2,5-dihydroxyterephtalate as the organic linker and the flexible response of the framework structure to external stimuli. Using acetic acid simultaneously as mediator and solvent leads to the reproducible formation of large NTU-9 crystallites after long reaction times. The MOF synthesis in isopropanol:acetonitrile (i-PrOH : MeCN) mixtures without a modulator is significantly faster but yields
