I wonder if the MOFs self assemble. I just started searching, but if any experts here know how they're made, please explain. I found an article that says the organic linkers are "ditopic or polytopic organic carboxylates (and other similar negatively charged molecules)," but MOFs are crystalline, so do they have to be baked? I get the impression that they're pretty easy to create, and can be designed to have affinity for any molecule. I really wonder if hydrogen storage will ever be solved. https://science.sciencemag.org/content/341/6149/1230444 https://science.sciencemag.org/content/341/6149/1230444
