“…This study demonstrated that extending the ligand does not affect the non-linear optical (NLO) properties, but the metalation showed noticeable impact as the limiting effect was improved in case of ZrPP-1-Co and ZrPP-1-Mn. Interesting variation on the structure packing was achieved through synthesis of a porphyrin bearing only two gallol units (5,15-di(3,4,5-trihydroxyphenyl)porphyrin or DGalPP) 115 (Figure 9c). Given the symmetry change on the linker, the resulting Zr-based MOF displays a different network although based on the same inorganic SBU as evidenced from PXRD structure determination (Figure 9f).…”

“…Additionally, Jiang and co‐workers reported a Zr‐MOF based on a ditopic polyphenolate linker DTPP (DTPP = 5,15‐di(3,4,5‐trihydroxyphenyl)porphyrin), Zr‐DTPP. [ 245 ] The channel in Zr‐DTPP is rhombus rather than square, which induces the DTPP units to form a staggering arrangement. The intermolecular π–π interaction between adjacent DTPP units stabilizes the porous structure of Zr‐DTPP.…”

“…[ 254 ] The J‐aggregated Zr‐DTPP shows superior properties in the photoinduced generation of singlet oxygen and selective photo‐oxidation of sulfides compared with the unaggregated Zr‐TTPP. [ 245 ] Zr‐MOFs have also been used for HER reaction. The redox‐active cobaloxime metallo‐linker based Zr‐MOF shows good electrocatalytic performance for at least 18 h.

Metal–Organic Frameworks Based on Group 3 and 4 Metals

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...

“…Given the broad applications of MOF photosensitizers, 1 O 2 quantum yield measurements of MOFs are crucial to quantitatively evaluate their efficiency for photochemical applications. However, there have been very few studies reporting 1 O 2 quantum yields of MOF-based photosensitizers . One challenge lies in accurately measuring the absorption spectra of MOF photosensitizers due to their insolubility in conventional solvents.…”

As a result, MOF particle suspensions have to be used in these measurements; however, traditional UV−vis spectroscopy does not account for the scattered light by a suspension sample, which inevitably leads to an overestimation of the amount of light being absorbed by the sample.…”

Determination of Singlet Oxygen Quantum Yield of a Porphyrinic Metal–Organic Framework

Metal–organic frameworks (MOFs) have emerged as heterogeneous photosensitizers in applications ranging from photodynamic therapy to photocatalysis. However, singlet oxygen (1O2) quantum yields of MOF photosensitizers are largely unknown. Herein, we report a reliable method to quantify the 1O2 quantum yield of a porphyrin MOF PCN-222/MOF-545 (free base). To accurately measure the optical density of the MOF suspensions in chloroform, a UV–vis spectrometer equipped with an integrating sphere detector was employed. However, no 1O2 near-infrared luminescence signal from the excited MOF could be detected and the amount of 1O2 produced by the MOF photosensitizer was quantified using a 1O2 trap 9,10-dimethylanthracene. Using C70 as a reference, the 1O2 quantum yield of PCN-222/MOF-545 (free base) was determined to be 0.35 ± 0.02. This method should be applicable to the determination of 1O2 quantum yields of other solid-state materials.
