Development and Characterization of Sr-Dextrin-Based Metal Organic Frameworks for Enhanced Catalytic Applications

This study presents the synthesis, structural characterization, and application potential of strontium-dextrin metal-organic frameworks (Sr-MOFs) using a single-step crystallization mechanism. In the synthesis process, the Sr atom functions as a pivotal connecting node, directly bonding with both carbon atoms and the organic linker to form the framework. The reaction between the organic linker and the corresponding strontium bromide precursor yields brown crystalline Sr-MOFs. Following synthesis, the crystals were collected, characterized, and evaluated for their thermal stability, solubility, and potential applications. Solubility tests indicated moderate dissolution in common organic solvents, facilitating further processing and application. Thermal analysis revealed that these Sr-MOFs remain stable in air up to 463 K, highlighting their suitability for high-temperature applications. This work underscores the potential of Sr-MOFs as versatile, thermally stable materials, expanding the utility of MOFs in fields that require biocompatible and robust structural frameworks.
