Room-temperature synthesis of highly porous M-6-oxocluster-based MOFs including 8- or 12-connected micro/mesoporous solids with different functionalized organic ligands was reported. The compounds showed varying degrees of defects while maintaining the chemical stability of the parent MOFs. The synthesis had a high space-time yield and provided the possibility to tune the particle size for practical use.
Room-temperature syntheses of metal-organic frameworks (MOFs) are of interest to meet the demand of the sustainable chemistry and are a pre-requisite for the incorporation of functional compounds in water-stable MOFs. However, only few routes under ambient conditions have been reported to produce metal(IV)-based MOFs. Reported here is a new versatile one-step synthesis of a series of highly porous M-6-oxocluster-based MOFs (M=Zr, Hf, Ce) at room temperature, including 8- or 12-connected micro/mesoporous solids with different functionalized organic ligands. The compounds show varying degrees of defects, particularly for 12-connected phases, while maintaining the chemical stability of the parent MOFs. Proposed here are first insights into in situ kinetics observations for efficient MOF preparation. Remarkably, the synthesis has a high space-time yield and also provides the possibility to tune the particle size, therefore paving the way for their practical use.
