Solvent-tuned ultrasonic synthesis of 2D coordination polymer nanostructures and flakes

• Combined ultrasound and solvent assisted synthesis of 2D coordination polymers. Role interstitial molecules in the delamination 2D-CPs. Influence sonication time nanostructuration processes. Morphological supramolecular transformations Herein, a new 2-dimensional polymer based on copper (II), {Cu 2 (L)(DMF) } n , where L stands for 1,2,4,5-benzenetetracarboxylate (complex 1 ) is synthesized. Interestingly, we demonstrate that both are relevant top-down fabrication nanostructures. Water intercalated suspended crystals complex modifying not only sphere Cu(II) ions but also final chemical formula crystalline structure obtaining {[Cu(L)(H O) 3 ]·H O} ). On other hand, required to induce nanostructuration. Remarkably, different morphologies obtained using solvents interconversion from one morphology another seems occur upon exchange. Both complexes as well corresponding nanostructures, have been fully characterized by means such infrared spectroscopy, x-ray diffraction microscopy.
