“…Taking advantage of unique fluorescence properties of rare earth (RE) elements including yttrium and lanthanides, RE-MOFs have been applied in broad applications, such as light emitting, [72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87][88] sensing, [89][90][91][92][93][94] catalysis, [95][96][97] and imaging [98][99][100][101][102] (Figure 3).…”

Metal-organic frameworks (MOFs), a class of porous crystalline framework materials, are linked by strong bonds between inorganic and organic building blocks. [1-3] In the past two decades, MOFs have rapidly grown as a star material due to their exceptional performance in areas such as storage, separation and catalysis. [4] The outstanding performance of MOFs in applications benefits from their intrinsically porous structures and highly tunable pore environment. [5-7] The creation and modification of pore space with optimized size, functionality and diversity can be precisely tuned at the molecular level by rationally designing building blocks and synthetic procedures. [8,9] The diversity of MOFs can be enriched by expanding the library of organic linkers with varying lengths, geometries, and functional groups. [10] Additionally, very diverse metal cations are applied to MOF synthesis, ranging from monovalent (Ag + , Cu + , etc.), divalent (Mg 2+ , Fe 2+ , Co 2+ , Ni 2+ , etc.), trivalent (Al 3+ , Sc 3+ , V 3+ , Cr 3+ , etc.), to tetravalent (Ti 4+ , Zr 4+ , Hf 4+ , etc.) cations. [11] In this review, we mainly focus on MOFs with group 3 and 4 metals, including Y, lanthanides (Ln, from La to Lu), actinides (An, from Ac to Lr), Ti, and Zr (Figure 1). Group 3 metal cations are generally found in the oxidation state of +3 in the MOF structures, while group 4 metal cations mainly exist in the oxidation state of +4, leading to the formation of much stronger coordination bonds with carboxylates. [12] Therefore, group 4 metal-based MOFs (M IV-MOFs) generally have enhanced stability compared with MOFs constructed from metals of group 3 and other groups. This series of MOFs stands out because the involved metals can generally coordinate with carboxylates to form frameworks with strong coordination bonds, according to the Pearson's hard/soft acid/base principle, where group 3 and 4 metal cations are regarded as hard acids while carboxylate ligands are hard bases. [11] One remarkable feature of MOFs with group 3 and 4 metals is that they generally can form phases containing M 6 O 8 (M = Y, Ln, An, Zr and Hf) clusters, regardless of their atomic numbers, charges and radius. This series of M 6-based MOFs is best represented by UiO series such as UiO-66 with fcu topology. [13] Under different synthetic conditions, UiO-66(M, M = An, Zr and Hf) constructed from [M 6 (μ 3-O) 4 (μ 3-OH) 4 ] clusters and linear carboxylates can be obtained, while UiO-66(M, M = Y, Ln) is assembled from Metal-organic frameworks (MOFs) based on group 3 and 4 metals are considered as the most promising MOFs for varying practical applications including water adsorption, carbon conversion, and biomedical applications. The relatively strong coordination bonds and versatile coordination modes within these MOFs endow the framework with high chemical stability, diverse structures and topologies, and interesting properties and functions. Herein, the significant progress made on this series of MOFs since 2018 is summarized and an update on the current status an...

“…The presence of metal sites, unsaturated in many cases, together with the presence of tunable pore sizes, make MOFs very suitable for catalysis of different reactions [110,111]. However, only photocatalyzed reactions will be discussed within this review, particularly water reduction (H 2 evolution reaction, HER), water oxidation (O 2 evolution reaction, OER) and CO 2 reduction.…”

“…The nature of the SAMs depends on the length of the carbon backbone and also, by the terminal functional organic group (-COOH, -NH 2 , -CH 3 ) that coordinates the metal centers of the MOF itself. For example, the iconic article reporting the synthesis of the first SURMOF [43], when a patterned SAM of 16-mercaptohexadecanoic acid and 1H,1H,2H,2H-perfluorododecane thiol on Au (111) was immersed into a clear reaction mixture typically used for synthesis of MOF-5 macrocrystals, a thin film of MOF-5 nanoparticles was obtained and selectively anchored at the carboxylate-terminated areas of the SAM, as shown in Figure 4.…”

“…3 Since the succinate linker (succ) has the particularity of being a flexible ligand, it can adopt different conformations when it is coordinated by a metal center under determined kinetic and thermodynamic conditions. 4 The interest in succinate-based coordination polymers has been a motivation for the exploration of structures employing lanthanides 4 and actinides. 5 In addition, from the crystal designing point of view, N-ancillary ligands such phenanthroline-like molecules, have shown antenna effect properties in photoluminescence (PL) for a variety of f-elements 6,7 based structures.…”
