Delamination of 2D coordination polymers : the role of solvent and ultrasound
Two novel cadmium-based 2D coordination polymers have been synthesized and characterized. Experimental results evidence that the best delamination processes occurs when weak interactions dominate the cohesion between layers and solvent molecules are occluded within the crystalline network. In this case, the delamination of the crystals occurs spontaneously in water. On top of that, and thanks to the high stability of the resulting (flake) colloidal dispersions, we have completed a detailed study of the sonication assisted delamination impact by: I) comparison of two different sonication approaches (bath vs. tip sonication) and II) optimization of final flake morphology and yield by controll…
Solvent-tuned ultrasonic synthesis of 2D coordination polymer nanostructures and flakes
Highlights • Combined ultrasound and solvent assisted synthesis of 2D coordination polymers. • Role of interstitial solvent molecules in the delamination of 2D-CPs. • Influence of the sonication time in delamination and nanostructuration processes. • Morphological and supramolecular transformations in 2D-CPs.
