“…For example, Shekhah et al have demonstrated the homogeneous, structurally well-defined HKUST-1 ([Cu 3 (btc) 2 ]) structures on a gold substrate, 299 and Nan et al have reported another LbL-based seeding method to prepare HKUST-1 on porous α-alumina supports. 300 In these cases, a bare substrate is first immersed into the linker solution. The linker-functionalized substrate is then further immersed in a metal precursor solution and subsequently in a solution of the organic ligand with a solvothermal treatment thus forming the first layer.…”

Materials fabrication with nanoscale structural precision based on bottom-up-type self-assembly has become more important in various current disciplines in chemistry including materials chemistry, organic chemistry, physical chemistry, analytical chemistry, biochemistry, colloid and surface chemistry, and supramolecular chemistry. Although the design of new materials based on nanoscale self-assembly is anticipated as a key concept, preparing complete three-dimensional structures at nanoscale precision remains a difficult target using current technologies. Rather, dimension-reduced approaches such as layering of two-dimensional nanostructures into precisely controlled lamellar nanomaterials are currently achievable. In particular, layer-by-layer (LbL) assembly is known as a highly versatile method for fabrication of controlled layered structures from various kinds of component materials using very simple, inexpensive, and rapid procedures. Therefore, fabrication of multilayer films through the LbL deposition process has attracted growing interest from various research communities. The high versatility and flexibility of LbL assembly is continuously creating new concepts, new materials, new procedures, and new applications. In this highlight review, we focus on nanoarchitectonics by LbL assembly. After an initial introduction on the invention and a brief history of the LbL assembly technique, innovations and the evolution of the technique are described based mainly on recent examples, which are categorized into two sections: (i) developments in methodology (technical, material, and phenomenological aspects with expansion of concept) and (ii) progress in applications (physical, chemical/biochemical, and biomedical applications).

“…[18] The growth of HKUST-1 onto a range of smooth surfaces such as polymeric, gold, ceramic, and quartz have been studied. [19] Using a step-by-step process, Nan et al [20] grew HKUST-1 onto porous α-aluminum discs, using 1:1 water:ethanol solvent system in a multistep process. In this work, HKUST-1 was grown on the surface of the three cross-linked electrospun membranes using ethanolic solutions.…”

range of applications. [1][2][3] It is a suitable polymer for the novice electrospinning to produce nanofibers as it is inexpensive, nontoxic, and water soluble. However, due to its water solubility, it needs to be stabilized, for example, by cross-linking to enable its practical application in waterbased environments to be realized. There are several studies demonstrating cross-linking of electrospun PVA membranes and their water stabilization. [4][5][6][7][8][9] Three major cross-linking methods have been described in the literature but each of these methods has its own problems in scaling up and cross-linking efficiency.(i) Immersion of electrospun membranes into an organic solvent (ii) Exposure of electrospun membranes to reagent vapor (iii) Addition of a cross-linker/catalyst to electrospinning solutionsThe first approach involving the use of an organic solvent is the simplest approach. Solvents such as Polyvinyl alcohol (PVA) is a water soluble polymer that requires further treatment to be stabilized before it can be used in aqueous environments. Electrospun PVA is cross-linked by incorporating cross-linking agents directly into the electrospinning solution followed by post-electrospinning thermal treatments to attain stability in aqueous environments. Previously published works on post-treatments include glutaraldehyde vapor exposure or soaking in organic solvents such as ethanol. However, these treatments incur lots of difficulties and hazards especially in scale production. In this study, with a view of imminent scale-up production required, fabricating electrospun cross-linked PVA is investigated without using catalysts, toxic vapor exposure, or solvent treatment. To produce cross-linked electrospun PVA membranes, citric acid, maleic acid, and polyacrylic acid are, respectively, added to PVA solution prior to electrospinning. Two potential applications are examined; the first is to use the membranes as produced for metal uptake in aqueous systems. The second application is for ammonia adsorption after decorating the membranes with a metal organic framework, copper benzene-1,3,5-tricarboxylate (HKUST-1).

CuBTC (Copper(II) benzene-1,3,5-tricarboxylate) is one of the most well characterized and widely studied metal organic framework (MOF) structures for potential use in industrial applications due to its relatively easy synthesis and excellent textural and physicochemical properties. In this comprehensive review, a different perspective on MOF materials for future sustainability is presented by critically examining the recent works that have considered the synthesis and adsorption/catalytic applications of CuBTC as a model case.
