Preparation of modified ZIF glasses. The utilized heating source was a hotplate (IKA C-MAG HS7 hotplate stirrer), upon which an aluminum block with drilled holes was positioned to ensure uniform heating of the quartz test tube (see Supplementary Fig. for an illustration of the setup). Approximately 0.2 g of ZIF crystal and varying amounts of salt (depending on the desired molar ratio R) were accurately weighed, and then ground using a mortar and pestle to achieve a homogeneous mixture. The mixture was subsequently transferred into the test tube, which was sealed with a soft plug. Argon gas was purged into the test tube to remove any air, and then the test tube was placed in the preheated aluminum block at a predetermined temperature for heating and melting of the mixture. Finally, the test tube was cooled to room temperature to obtain the hybrid glass by simply removing the quartz tube from the aluminum block.
