“…Compared to AuPc and AuPc(CN) 8 , AuPc(COOH) 8 is characterized by new bands at 1703 and 1233 cm -1 , corresponding to νC=O and νC-O stretching vibrations. 31 From Fig. S2, the presence of the broad band between 2300 and 3600 cm -1 further corroborates the obtaining of the AuPc(COOH) 8 material.…”

“…Specifically, the band at 720 cm -1 for νC-H 23 decreases in intensity for AuPc(CN) 8 and AuPc(COOH) 8 , which is explained by the substitution of half of the hydrogens of AuPc. The presence of a new band at 2220 cm -1 , assigned to the vibrational CN groups in MPc, 15,31,32 confirms the synthesis of the AuPc(CN) 8 material. The presence of this band in the spectrum of AuPc(COOH) 8 indicates the presence of the parent AuPc(CN) 8 and not a partial hydrolysis of all CN groups, since, as we will see later, the mass spectrometry confirms the expected mass.…”

Gold phthalocyanine-based materials can allow to combine the unique physical properties of the metallophthalocyanine with gold for numerous applications such as (photo)-electrochemistry or the so-called single atom catalysts (SACs), which require very small amounts of metal. However, there is currently a lack of physico-chemical and electrochemical knowledge to consider such applications. We report the synthesis and the physical characterization of three types of materials, the unsubstituted and the octo-substituted gold phthalocyanines AuPc, AuPc(CN)8 and AuPc(COOH)8, which were successfully synthesized. To interrogate the physicochemical and electrochemical properties of the as-synthesized materials, we have performed a multi-variant study by integrating different methods (UV–vis, FTIRS, TGA-TDA, HR-ESI-MS, SEM-EDX, XRD, XPS, CV). UV–vis confirms the shift towards high wavelengths (bathochromic effect) for the transition Q-band (charge transfer from pyrrolic carbons to neighboring atoms in the macrocycle) of AuPc(CN)8 and AuPc(COOH)8 compared to AuPc. CV in both aqueous and non-aqueous provides the first electrochemical insights into the phthalocyanine ring reduction and oxidation, AuPc/[AuPc]−, [AuPc]−/[AuPc]2− and [AuPc]2−/[AuPc]3−. The results delineate a possible rational pathway for AuPc-based materials or alternatively, their transformation into SACs, where a single Au atom is embedded in a nanostructured carbon-nitrogen scaffold.

“…A common example of a model reaction is the photooxidation of 1,5-dihydroxynaphthalene (DHN) to 5-hydroxy-1,4-naphthalenedione (juglone), with MOFs or COFs acting as the catalyst. 94 Singlet oxygen ( 1 O 2 ), which is produced when an electron is excited from a photoactive MOF or COF, plays a significant role in the reaction between DHN and juglone upon light irradiation. In this case, because of their well-known photoredox ability and high light-harvesting efficiency, porphyrin derivatives have been utilized extensively in photochemistry for the production of 1 O 2 .…”

“… , Regarding to the metal nodes, metal ions are generally coordinated with organic linkers as well as some solvent molecules . Usually, the solvent molecules can be removed through evacuation or heating treatment without destroying the framework structures, which results in the generation of coordinatively unsaturated metal centers (also noted as defect engineering of MOFs) that can work as Lewis acid sites to facilitate the acceptance of electrons as well as promote the catalytic conversion. − Regarding to the organic linkers, some molecular catalysts, such as porphyrins, − phthalocyanines, ,, and salens, − have been employed as building blocks of MOFs to improve their catalytic performance.…”

The electrocatalytic carbon dioxide reduction reaction (CO 2 RR) holds great potential in promoting carbon neutral through effectively converting CO 2 molecules to useful chemicals and fuels. The high-efficiency electrochemical conversion of CO 2 to single-carbon products has been well realized, while more efforts are needed for the generation of high-value multicarbon products. Metal−organic frameworks (MOFs), featuring porous structures, high chemical tunability, and ultralarge surface area, have attracted increasing attention in the electrochemical CO 2 RR. Herein, we review the recent progress of electrocatalytic CO 2 RR on MOF-based materials toward multicarbon products. First, the structure of MOFs is briefly introduced. Then, the electrocatalytic CO 2 RR performance and the corresponding catalytic mechanism of pristine MOFs (classified according to the kind of organic ligands/linkers) and MOF-derived materials (including metal nanomaterials, single-atom catalysts and nanocomposites) toward the multicarbon product generation are systematically discussed. Finally, critical challenges and potential opportunities are highlighted to inspire the rational design and targeted synthesis of advanced MOF-based materials for high-performance electrocatalytic CO 2 reduction toward multicarbon products.
