The ZIF-8 samples were synthesised and then immersed in DMF, deposited in methyl alcohol, and dried at 80 ºC . propane).BF4. Additionally, the structure of the synthesised polymer was unique from that of polymers made using conventional techniques. According to this study's findings, ILs may be a promising new type of pure and active solvent for the synthesis and crystallisation of coordination polymers . Recently, the synthesis of HKUST-1 was studied using a microfluidic system. Cu (OAc) is used to make the aqueous phase. H3BTC was dissolved in 1-octanol at 60 ºC and then combined with 2H2O and polyvinyl alcohol in water at room temperature to produce the organic ligand complex. They used syringe pumps to deliver immiscible liquids to T-junction where they mixed to produce an aqueous solvent and an organic combination. These droplets passed through hydrophobic polytetrafluoroethylene tubes before being collected in ethanol, producing the HKUST-1 MOF . It is feasible to create three different core-shell MOF composites:
