Inorganic and organic glass materials exhibit remarkable versatility in processing, with their abilities to be shaped into various forms and for their chemical compositions to be continuously tuned . An important family of organic-inorganic hybrid materials, metal-organic frameworks (MOFs), have not yet achieved the same level of processability and continuous composition tunability . MOFs offer exciting prospects for their uses as, e.g., catalysts 3 , gas adsorbers , and electrolytes , especially enabled by their high porosity (surface area up to >10,000 m 2 g -1 ) 4, 7, 8 , but their practical applications are often hindered by poor processability as they are typically only available in powder form .
