Towards optical application of metal-organic frameworks: Cu-MOFs as sole heterogeneous photocatalyst for arylation of phenols at room temperature

Photoelectroactive metal–organic frameworks

“…Phenol and the corresponding derivatives (Scheme 7) have been widely investigated for photodegradation. 231–238 For instance, Ag 3 PO 4 @UMONs was prepared by the integration of Ag 3 PO 4 and UMONs (constructed from mixed metal salts of NiCl 2 ·6H 2 O and CoCl 2 ·6H 2 O and H 2 BDC) and exhibited phenol degradation (40 mg L −1 , 100%) within 16 min under visible light irradiation (>420 nm). 231 A core–shell structure with Ag 3 PO 4 inside bimetallic UMONs showed synergistic effects for boosting charge transfer and good separation for improved performance as compared to Ag 3 PO 4 .…”

“…It is also worth mentioning that a pristine Cu MOF constructed from Cu(NO 3 ) 2 ·3H 2 O, H 2 BDC and 1,4-diazabicyclo[2.2.2]octane was reported to transform phenols into diaryl ethers under 365 nm UV light irradiation. 236…”

Photogenerated Charge Separation in a CdSe Nanocluster Encapsulated in a Metal–Organic Framework for Improved Photocatalysis

“…Metal organic frameworks (MOFs) are a class of microporous or mesoporous crystalline solid materials in which the lattice is made by connecting inorganometallic nodes (which may be, e.g., metal cations or metal oxide clusters) with organic linkers. − MOFs have received a great attention because of their unique advantages for a variety of applications including catalysis, , gas separation, , gas storage, and energy storage . In recent years, it has been proposed to design MOFs for photocatalysis by taking advantage of their structural flexibility, stability, tunability, large surface-to-volume ratios, and well-separated and well-exposed adsorption sites. − …”

Recent Advancement of Ullmann Condensation Coupling Reaction in the Formation of Aryl-Oxygen (C-O) Bonding by Copper-Mediated Catalyst

“…Hwang Jong Kook observed that dimethylformamide (DMF) preferably forms a hexagonal rod MOF (ZBDh) and methanol preferably forms a tetragonal plate MOF (ZBDt) (Figure 11)[102]. This Cu-MOF utilized as a heterogeneous photocatalyst for the arylation of phenol in the presence of t-BuOLi as a base and acetylacetone as a ligand under 365 nm light at rt(Table 7)[101]. Synthetic route of Cu2(BDC)2(DABCO).…”

“…(a) ZBD with a hexagonal framework (ZBDh), (b) ZBD with a Synthetic route of Cu 2 (BDC) 2 (DABCO).Catalysts 2020, 10, x FOR PEER REVIEW 26 of UiO-66-NH2-Mlm/CuO nanoparticle catalyzed synthesis of biphenyl ethers. Later on, Hiep Q. Ha's team synthesized MOF-supported copper catalyst Cu2(BDC)2(DABCO)using benzene-1,4-dicarboxylate (BDC) and 1,4-diazabicyclo (2.2.2) (DABCO) in dimethylformamide (Scheme 33)[101]. The solvent-mediated method strongly affected the morphology of nano-MOF.…”
