A quinoline-based covalent organic framework (N^N)-Q-COF was constructed with chemically stable networks and (N^N)-sites. Its coordination bond with Ir(C^N)2(N^N) units generated new entities with exciting photophysical properties; particularly, the incorporation of a coumarin ligand greatly elevated its properties to a higher level. The further anchoring of NiCl2 produced structures merging both photoredox and organometallic catalysts, resulting in excellent photocatalytic activities in C–S and C–N cross-coupling synthesis. The organic integration of Ir(C^N)2(N^N), NiCl2, and COFs and the advantages of COF networks were responsible for this transcendent dual catalysis. The chemical stability of Q-COFs and the coordination anchoring of Ir(C^N)2(N^N) and NiCl2 enabled its recycling and reuse with no reduction in catalytic performance. [ABSTRACT FROM AUTHOR]

Anderson-type polyoxometalates have exhibited remarkable catalytic capabilities in a wide range of reactions. This discourse delves into the distinct categories of Anderson POMs and their respective catalytic reactions, which are examined in separate segments. These encompass the straightforward {XMo6} POMs, the organic grafting {XMo6} POMs, and the integration of POMs into POM cluster organic frameworks. It is important to highlight that specific catalytic functionalities can solely be accomplished via the utilization of Anderson-type POMs, thus emphasizing their indispensable role in future explorations.

Covalent organic frameworks (COFs) have emerged as significant candidates for visible-light photocatalysis due to their ability to regulate performance which is achieved through the careful selection of building modules, framework conjugation, and post-modification. This report focused on the efficient transformation of an imine-linked I-COF into a π-conjugated quinoline-based Q-COF, which enhanced both the chemical stability and conjugation of the network. By methylating the pyridyl groups in the Q-COF, an N+-COF was obtained. Subsequently, the Ru(N^N)3-photosensitizer ([Ru(dcbpy)3]4−) was incorporated into the channels of the cationic N+-COF through electrostatic interactions, resulting in the formation of [Ru(dcbpy)3]4−⊂N+-COF. This composite exhibited exceptional photocatalytic activity, demonstrating high yields and selectivity in the oxidation of sulfides or amines to their respective products. [ABSTRACT FROM AUTHOR]

The chemistry of polypyridyl Ru(II) and cyclometalated Ir(III) derivatives provides long-lasting interest to researchers due to the inherent advantage of their triplet states in a variety of photoactivities. The introduction of Ru(N^N)3 and Ir(C^N)2(X^N) modules into well-defined architectures extends the research areas of both photoactive metal complexes and network chemistry, generating a lot of new opportunities with interesting structural aesthetics and profound functional possibilities. The rapid development of research in integrating Ru(II) or Ir(III) metallotecons into the architectures has been apparent in recent years which makes this a fascinating subject for reviewing. This review focuses on the design and syntheses of Ru(N^N)3 and Ir(C^N)2(X^N) functionalized architectures of metal–organic frameworks (MOFs), covalent–organic frameworks (COFs), metallasupramolecules, organic supramolecules and supramolecular organic frameworks (SOFs). Furthermore, the photocatalytic applications including the hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), photocatalytic oxidation and photoredox catalysis of organic transformation are also presented.

The stable Zr6‐based coordination framework Ru‐1 was assembled via the linkage of Zr6‐organic layers and photosensitized Ru(N^N)3‐metalloligand. Based on its 1D open channel and the incorporation of Ru(N^N)3‐photosensitizer, it can serve as a highly efficient heterogeneous catalyst in the aerobic photooxidation reactions, including photooxidation of sulfides, coupling of amines and oxidative hydroxylation of arylboronic acids. The stability and catalytic performance of recycled Ru‐1 was also explored. [ABSTRACT FROM AUTHOR]

Using the photosensitized Ru(N∧N∧N)2-metalloligand, a series of Ce frameworks were synthesized. The incorporation of the visible-light-responsive Ru(N∧N∧N)2-unit endows the Ce frameworks with photocatalytic activities in both sulfide oxidation and hydrogen production. The doping of Zr and particularly the oxidation state of Ce has great influence on the photocatalytic properties of the Ce frameworks. [ABSTRACT FROM AUTHOR]

Three isostructural lanthanide metal‐organic frameworks (Ln‐MOFs) were synthesized with uncoordinated N^N site, and the Ru(N^N)3 photosensitizer was introduced via coordination link. These functionalized frameworks showed excellent performance in the photocatalytic oxidation of sulfides with good conversion and high sulfoxide selectivity. [ABSTRACT FROM AUTHOR]

A series of metallarectangles 1–5 were synthesized by the selective combination of (p-cymene)Ru-corner, bis(β-diketone) arms and bifunctional pyridyl linkers. They exhibited a very rare phenomenon of haloalkane-induced fluorescence enhancement. [ABSTRACT FROM AUTHOR]
