Sequence control of metals in MOF by coordination number precoding for electrocatalytic oxygen evolution

Metal–organic frameworks based on infinite secondary building units: recent progress and future outlooks

“…Metal-mixing is a common but effective strategy to enhance performances by combining both merits of the homometallic analogies. 20,31,123 Schroder and his colleagues 31 constructed a heterometallic 1D MFM-300(Al 0.67 Cr 0.33 ) for SO 2 separation from CO 2 , which was compared in parallel to its homometallic MFM-300(Al) and MFM-300(Cr). According to the experimental results, MFM-300(Al) showed both stronger adsorption toward SO 2 and CO 2 but at the compromise of lower SO 2 /CO 2 selectivity than MFM-300(Cr).…”

“…[7][8][9][10][11] In most cases, the metal ions or metallic secondary building units (SBUs) are considered as discrete zero-dimensional (0D) nodes that are further linked by organic ligands for the construction of frameworks. [12][13][14][15] Distinctly, innite SBUs (ISBUs) like onedimensional (1D) chains, [16][17][18] two-dimensional (2D) sheets, [19][20][21] and even three-dimensional (3D) nets [22][23][24] have also emerged in MOFs and been rapidly developed recently. Consequently, MOFs can also be categorized into OD, 1D, 2D, and 3D subclasses according to the ISBU types (Scheme 1).…”

Reconstructured Electrocatalysts during Oxygen Evolution Reaction under Alkaline Electrolytes

“…To accomplish the understanding of the genuine structure‐activity correlation, it is essential to study in‐depth the interaction between substrate materials and active species. The nature of the reconstructed species is influenced by the composition, structure, porosity, crystallinity, and other conditions of the substrate [45–46] . Meanwhile, the substrate materials may influence the OER performance by modulating the adsorption/desorption capacity of the active species with the reaction intermediates through electron transfer and interfacial interaction.…”

Smart Tetraphenylethene‐Based Luminescent Metal–Organic Frameworks with Amide‐Assisted Thermofluorochromics and Piezofluorochromics

“…[11][12][13][14][15] Transplanting dynamic motifs such as organic ligands with moving moieties (e.g., rotary, vibrational, or elastic elements) into chemically rigid frameworks to derive artificial molecular machinery has been a transformative approach for designing novel smart materials. [16][17][18][19][20][21][22][23][24][25] As compared to conventional luminescent MOFs, the presence of these molecular machinery elements provides attentional and unprecedented responsiveness. Aggregation-induced emission (AIE) fluorogens (AIEgens) are a novel class of organic fluorophores, whose emission is largely associated with their twisted molecular geometry and degree of intramolecular motions.…”
