Abstract MOFs are typical 3D crystalline materials, and amorphous MOFs emerges as a new attractive material family very recently. Herein, we report a novel layered MOF, IPM-1, which is synthesized from a cage-like organic linker with extremely weak interlaminar interaction. When subjected to external disturbance, IPM-1 degraded to an intermediate state between the crystalline and amorphous phase (1D-amorphours), in which the layers retain the in-plane two-dimension periodic structure but are misaligned in the third dimension, leading to the loss of apparent porosity and crystallinity. 1D-amorphous IPM-1 is readily exfoliated into crystalline 2D nanosheets with a thickness of 1.15 nm at gram-scale, excellent uniformity and homogeneity, lateral size up to 10 µm, and restored microporosity. They can fabricate wafer-scale thin films and present the first mass-producible 2D monolayer material. This work underlines that MOFs without apparent crystallinity can be idea precursors for the successful preparation of 2D crystalline monolayer nanosheets.

Hemoperfusion has become the third-generation treatment strategy for patients suffering from hyperbilirubinemia, but adsorbents used for bilirubin removal mostly face intractable problems, such as unsatisfactory adsorption performance and poor hemocompatibility....

Organic Framework

Three new metal-organic framework materials [Mg3(LH)2(EtOH)2(H2O)]·(EtOH)4.5(H2O)0.25 (IMP-13Mg), [Co3(LH)2(EtOH)2(H2O)]·(EtOH)3 (IMP-13Co), and [Ca3(LH)2(EtOH)4]·(EtOH)6 (IMP-14) have been prepared from the treatment of silanetetrabenzoic acid (L-H4) with MgII, CoII, and CaII salts respectively. In all cases the silanetetrabenzoic acid has been triply deprotonated and the resultant carboxylate groups assemble with trinuclear metal-based nodes to give (3,6)-connected kgd-type two-dimensional layers. These layers are then extended into the third dimension by coordination of the metal nodes by carboxylic acid groups in adjacent layers. In the case of IMP-13Mg/Co, only alternate L-H connectors and metal nodes are involved in these interlayer interactions, leaving some acid groups free within the structure. However, in IMP-14 all L-H connectors and metal nodes participate in interlayer bonding.

We successfully demonstrate that the chemical bath deposition (CBD) method is a versatile method for synthesizing phase-pure and uniform MOFs by controlling their nucleation stages and pore structures.
