A non-covalent “click chemistry” strategy to efficiently coat highly porous MOF nanoparticles with a stable polymeric shell

Site‐Specific Surface Functionalization via Microchannel Cantilever Spotting (µCS): Comparison between Azide–Alkyne and Thiol–Alkyne Click Chemistry Reactions

“…Functionalization of surfaces and materials through the covalent attachment of organic monolayers has become the focus of much research in the last decade because of numerous applications in chemical/biological sensing, drug delivery, selective gas separation, cancer detection, etc. In this regard, click chemistry reactions – which were introduced by Kolb et al in 2001 – are excellent candidates due to having unique characteristics such as mild reaction conditions, high efficiency, compatibility with different kinds of solvents specially water, high reaction rate, and easy post‐treatment and are thus used for many applications …”

New insights on the supramolecular structure of highly porous core–shell drug nanocarriers using solid-state NMR spectroscopy

“…1,2 Among them, iron trimesate nanoMOF MIL-100(Fe) (MIL stands for Material of Institute Lavoisier) is among the most promising candidates for efficient drug incorporation by a one-step organic solvent-free method and for surface coating with cyclodextrin (CD) molecules which can be further engineered by linking phosphates (CD-P), targeting moieties or polymers. 3,4 The interactions of surface-modied iron trimesate nanoMOFs with cancer cells were increased by means of these versatile "Lego"-type coatings. 3 If the potential applications of the CD-P coated nanoMOFs have been demonstrated, 1,5 little information is known about the interactions at the atomic level between the CD-P coating and the nanoparticle (NP) surface sites.…”

Cyclodextrins Modified/Coated Metal–Organic Frameworks

“…For example, the chemical structures of organic struts for preparing MOFs can be characterized by 1 H NMR [17], some particular functional groups such as azobenzene moieties on precursors of MOFs can be determined by UV spectra [17,24], and phosphate groups can be checked by 31 P NMR [23,27]. The employment of the same characterization methods and instruments in different processions of building advanced materials could always have different purposes, for example, powder X-ray diffraction (PXRD) patterns are adopted to compare with simulated data from the single X-ray crystal structure of MOFs [17,[23][24][25][26][27], and also very direct proofs for confirming the crystallinity of CDs-modified MOFs [18,20,21]. In this section, we will discuss different characterization methods and instruments according to different purposes during diverse processions of the construction of CDs-modified/coated MOFs including preparing MOFs, studying interactions between CDs and MOFs, as well as confirming the integrated hybrid materials.…”

“…The crystalline structures of MOFs can be directly revealed by single-crystal X-ray diffraction studies [17]. Nitrogen sorption measurement of MOFs can be used for checking their permanently porous nature by the Brunauer-Emmett-Teller (BET) analysis [17,[20][21][22][23][24]26]. Additionally, the pore size distribution can be determined by density functional theory [17].…”

“…In this review, we briefly introduced the stable and highly porous CDs-modified/coated MOFs (Schemes 1 and 2, Table 1) [17][18][19][20][21][22][23][24][25][26][27][28]. Bridging CDs and MOFs chemistry is very challenging, and researchers with various backgrounds such as supramolecular chemistry, metal ligated materials and polymeric chemistry have done valuable contributions in this arising area.…”
