“…Looking to expand the number of available Sn( ii ) alkoxide precursors for subsequent OR/H metathesis ( en route to bulk Sn metal), we targeted the preparation of ImMe 2 ·Sn(O t Bu) 2 ; added motivation for using the small carbene ImMe 2 stems from possible enhanced volatility of the final adduct for future studies involving atomic layer deposition (ALD). 13 Following established literature procedures, 8 b ,14 the free carbene ImMe 2 was generated in situ and combined with tin( ii ) dichloride in a THF solution to produce ImMe 2 ·SnCl 2 ( 2 ) (Scheme 2). Crystals of 2 were obtained from a concentrated THF solution (Fig.…”

“…Different gas‐phase precursors are alternately passed through the reactor to complete the physical and chemical adsorption or surface reaction on the substrate to generate MOF membranes. [ 62 ] Compared with CVD, ALD can better control the thickness of MOF membranes by the “self‐limiting” surface reactions. In addition, ALD relies on the continuous and self‐saturating surface gas reactions.…”

Metal-organic frameworks (MOFs) are porous crystal frameworks constructed by metal clusters and bridging organic ligands. [1] This class of materials not only has a highly tunable and regular pore structure, variable functionality, and internal connectivity, [2] but the superior designability enables them to accommodate the introduction of a variety of functional sites on frames, cavities, and channels. [3] These make them have important applications in many fields, including drug delivery, [4] adsorption, [5] antimicrobials, [6] electron conduction, [7] gas storage, [8] catalysis, [9] sensing, [10] and energy conversion. [11] MOFs were first developed by Hoskins and Robson via connecting discrete metal clusters and reappraising the Zn(CN) 2 and Cd(CN) 2 structure [12] and then termed MOFs in 1995. [13] Recent researches focus on the modulation of MOF chemistry to expending our understanding of the relationship between the MOFs structure, function, and applications. However, the poor adhesion and heterogeneous distribution of powdery MOFs hindered their detection in many applications. So, the development of the commercialization of MOFs was limited. [14] Membrane is a kind of material with small pore size and large specific surface area. [15] A series of structural features facilitate its rapid transfer of matters with the action of external driving forces in the field of biomedical, [16] energy storage, [17] and environmental protection. [18] The preparation of MOFs into membranes will play their role to the maximum extent [14,19] and endow more precisely pore size, pore structure, and molecular-/ion-specific groups with the membranes. [20] MOF membranes are mainly divided into two categories: pure MOF membranes and MOF/polymer hybrid membranes. Pure MOF membranes are the continuous thin layers of MOFs that are formed by growing (or depositing) on a porous support layer and/or inorganic substrate or a porous polymer substrate. These kinds of MOF membranes have the advantages of good thermal stability, high mechanical property, antifouling, antiswelling, and controllable pore structure. [21] As pure MOF membranes are composed of MOFs, the permeability and selectivity are completely determined by the pore sizes of MOFs, which endow pure MOF membranes with significant selectivity. [22] Pure MOF membranes should have the best performance in theory. However, their brittle texture, high cost, and difficulty in chemical modification still limit their practical applications. MOF/polymer hybrid membranes are composite materials that are composed of a dispersed phase (MOFs) and a continuous phase (polymer or another flexible matrix). There are two forms: MOFs embedded in the polymer matrix and MOFs on the surface of the flexible substrate. The thickness is much thicker than the diameter of the embedded porous MOFs; thus, the doped MOFs are surrounded by the polymer matrix. In this case, the selectivity and permeability of the MOF/polymer hybrid membranes are significantly dependent on the properties of the
