“…Very recently, our group reported the attachment of Pt II -hydroxyquinoline fragments in defective sites of an imine-based COF structure. This metal fragment acted as photocatalytic center showing TON up to 8,000 with excellent stability and recyclability ( López-Magano et al, 2020b ). c) Dehydrogenation of Secondary Amines: The selective oxidative dehydrogenation of secondary amines to imines is feasible due to the impossibility of the substrates to generate nitriles, but is limited by the steric hindrance around the N−H bond.…”

“…This reaction has been achieved by the following materials: a) three new benzoxazole-linked COFs, ( LZU-190 ) obtained in 2018 ( Wei et al, 2018 ), b) an imine-linked COF obtained in 2019 through the self-condensation of an aldehyde and amine containing tetratopic building block, ( Wojaczyńska and Wojaczyński, 2010 ; Lu et al, 2019 ; Lu et al, 2020 ), c) three imine-based undecorated COFs with different architectures and morphologies ( Huang et al, 2017 ). e) Oxidative Coupling: Firstly, the coupling imine product from primary amines was obtained using Por-sp 2 c-COF (porphyrin-containing COF) as photocatalyst combined with TEMPO as co-catalyst and oxygen as the final oxidant ( Chen et al, 2019a ; Chen et al, 2019b ; Liu et al, 2020a ; López-Magano et al, 2020b ). Also, benzylamine was oxidized using TFPT-BMTH (hydrazone-based COF) and water as solvent.…”

Covalent Organic Frameworks (COFs) and related extended organic materials have been widely used as photocatalysts in the last few years. Such interest arises from the wide range of covalent linkages employed in their construction, which offer many possibilities to design extended frameworks and to link photoactive building blocks. Thus, the potential utility of predesigned organic photoactive fragments can be synergistically added to the inherent advantages of heterogeneous catalysis, such as recyclability and easy separation of catalyst. In this overview, the current state of the art on the design of organic materials for photocatalytic oxidation reactions will be presented. The designing process of these materials is usually conditioned by the generally accepted concept that crystallinity and porosity defines the quality of the heterogeneous catalysts obtained. The care for the structural integrity of materials obtained is understandable because many properties and applications are intimately related to these features. However, the catalytic activity does not always directly depends on these characteristics. A critical compilation of the available literature is performed in order to offer a general perspective of the use of COFs and Covalent Triazine Frameworks (CTFs) in photocatalytic oxidation processes, including water oxidation, which constitute an important outcome relevant to artificial photosynthesis.

“…[76] It is obvious that the "postmodification" strategy and "bottom up" strategy are (Scheme 34, a, b). [77][78] In Ma's report, two ortho-hydroxyl groups were introduced into COFs (VO-TAPT-2,3-DHTA COF, Figure 7, Table 6) to coordinate with VO 2 + in traditional way, which then catalyzed the sulfide oxidation with t-BuOOH as oxidant. Plausible mechanism was also studied (Scheme 35).…”

Covalent organic frameworks (COFs), which are built upon dynamic covalent chemistry (DCC) with various organic building blocks, possess predesignable, highly ordered and crystalline porous structures. These features endow COFs with great potential in the development of function‐tailored materials, particularly in catalytic organic synthesis. Start from selective oxidation reactions early introduced by Ferdi, Thomas and their co‐workers, and then Wang and co‐workers performed Suzuki‐Miyaura reaction through integrating palladium into COFs, increasing numbers of works were established to explore their potentials in the 4.5catalysis of organic reactions. As heterogeneous organic catalysts, COFs bring benefits and solve problems, but also create new obstacles. Hence, we would like to establish a comprehensive system to review some pioneering works in this area. This will help us get a better view so that we can discuss the key and challenging issues we are currently confronted with.

To meet the increasing demand for environmentally benign and sustainable chemical processes, the use of light in organic synthesis is blossoming. Over the past decades, luminescent transition metal complexes have been extensively studied as photosensitizers due to their excellent photophysical properties and flexibility in structure modification. The visible‐light photo‐catalysis has been developed rapidly, from “proof of concept” to “a useful strategy,” in a broad range of organic transformation reactions that can be used in practical organic synthesis. Compared with the extensive literatures on ruthenium and iridium complexes used in visible‐light catalysis, the summaries on gold, platinum tungsten (except polyoxotungstates), and osmium complexes catalyzed photochemical reactions are scarce. In this article, the recent developments in photochemical reactions catalyzed by gold (Au), platinum (Pt), tungsten (W), and osmium (Os) complexes, as well as the mechanistic studies and their applications in organic synthesis are summarized. The photochemical reactions discussed herein mainly refer to the ones with transition metal complexes that absorb light in the UV–visible spectral region and which serve as a photo‐redox catalyst or a photosensitizer.
