Digital Control of Multistep Hydrothermal Synthesis by Using 3D Printed Reactionware for the Synthesis of Metal–Organic Frameworks

다국어 초록 (Multilingual Abstract)

Hydrothermal‐synthesis‐based reactions are normally single step owing to the difficulty of manipulating reaction mixtures at high temperatures and pressures. Herein we demonstrate a simple, cheap, and modular approach to the design reactors consisting of partitioned chambers, to achieve multi‐step synthesis under hydrothermal conditions, in digitally defined reactionware produced by 3D printing. This approach increases the number of steps that can be performed sequentially and allows an increase in the options available for the control of hydrothermal reactions. The synthetic outcomes of the multi‐stage reactions can be explored by varying reaction compositions, number of reagents, reaction steps, and reaction times, and these can be tagged to the digital blueprint. To demonstrate the potential of this approach a series of polyoxometalate (POM)‐containing metal–organic frameworks (MOFs) unavailable by “one‐pot” methods were prepared as well as a set of new MOFs.
Digitale anorganische Chemie: Mit 3D‐Druck lassen sich digital definierte und strukturierte Reaktoren für mehrstufige Hydrothermalsynthesen aufbauen. Dieser Ansatz erhöht den Parameterraum und die kinetische Kontrolle während eines hydrothermalen Prozesses und ermöglicht so die Synthese einer Serie Polyoxometallat‐haltiger Metall‐organischer Gerüste (MOFs), die durch Eintopfmethoden nicht erhältlich sind.
