权利人:UNIV MADRID AUTONOMA
摘要:The present invention relates to the field porous crystalline materials, more particularly to metal organic frameworks (MOFs) and covalent organic frameworks (COFs). According to this invention, micelles are used as nanoreactors for the synthesis and stabilisation of porous crystalline materials in aqueous dispersions. Disclosed are dispersions comprising such porous crystalline materials, the synthesis and use of such dispersions. Further disclosed are novel porous crystalline materials, the synthesis and use of such crystalline materials. Further disclosed are novel inks comprising the dispersions and non-solvent, the synthesis and use of such inks for direct printing, 2D printing and 3D printing.
