Abstract Covalent Organic Frameworks (COFs) represents a class of remarkable porous materials composed of organic building blocks that are covalently linked in a periodic manner to form crystalline structures. High surface area, high porosity, tunable pore size, and high stability are their exceptional properties, which make them attractive candidates for various applications in the fields of catalysis, energy storage devices, biomedical applications, gas separation and storage applications. In fact, the great interest shown in COFs gave us a stimulus to review the output of the recent substantial efforts in this area. Meanwhile, the development of portable and sophisticated systems based on these particles is believed to create deeper insights for the scientists to embark on new investigations to pave the way for discovering new fundamental characteristics of COFs, modifications. Furthermore, the effect of modifications/fractionalizations on the performance of COFs will be thoroughly explained and challenging problems are mentioned. Moreover, the paper covers an inclusive collection of referenced recent research articles, providing readers with a comprehensive understanding of the subject matter and an extensive bibliography for further exploration. Through this comprehensive overview, the paper alleviates the noteworthy contributions of COFs in driving innovation and progress in a range of key scientific disciplines.

Abstract Hydrogels are widely used in various areas of human life. The vast majority of hydrogel materials used are polymer-based. Despite a number of advantages compared to polymer-based materials, studies on inorganic hydrogels are very limited and scattered. They are rarely offered as a basis for development of new functional materials. This review is an attempt to draw attention of researches to inorganic hydrogels. It describes currently existing methods for the synthesis of such hydrogels, their properties, and shows possible applications of the hydrogel materials.

Abstract Acyclic diaminocarbenes (ADCs)–Metal complex having strong donor ability and thermal stability led to extensive usability across every area of inorganic and organometallic chemistry. The unique properties of acyclic diaminocarbenes (ADCs) provide certain advantages over other carbene ligands and have the potential to make a great impact in catalysis. Further, the straightforward synthesis of M–ADCs (metal bound acyclic diaminocarbenes) complexes via metal-mediated reaction provides a wide range of well-defined metal carbene catalysts, which might inspire more researchers to devise unsymmetrically substituted, chiral, and novel acyclic carbene compounds. Although the above synthetic route is limited to a few late transition metals, but have great opportunities to expand the scope of this method. The application of M–ADCs complexes as a catalyst for several organic transformation reactions such as various cross-coupling reactions and asymmetric synthesis like hydroarylation, hydroazidation, hydroamination, cyclization and addition reactions which have shown comparable or even higher activities than the analogous M–NHCs based on all the reports presented. Recent findings of donor ability of several ADC ligands would be useful in fine-tuning the electronic properties, and then a catalyst with a certain combination of donicity and steric requirement could open new doors in catalytic reactivity. Thus, the objective of this review is to assess the recent growths that have been made in designing novel and chiral ADCs ligands and synthesizing ADCs–Metal complexes and to highlight catalytic activities of metal acyclic diaminocarbene complexes for cross-coupling reactions.

Abstract This review explores the role of 2-(2′-Pyridyl)imidazole (PyimH) as a coordinating ligand and also its role as a supramolecular agent through hydrogen bonding and π⋯π interaction. Two N coordination sites make 2-(2′-Pyridyl)imidazole an analogous ligand to 2,2′-bipyridine. The syn orientation of imidazole and pyridine sp 2 nitrogen makes it a bidentate chelating ligand. PyimH mainly produces discrete coordination complexes (0D), but in a few cases, 1D coordination polymers are observed due to bridging co-ligands like oxalate, dicyanamide, tricyanomethanide, croconate, thiocyanate, and iso-thiocyanate. These discrete coordination units and co-ligand bridged 1D coordination polymers are further augmented to higher dimensional supramolecular systems having linear, zig-zag, ladder-shaped, ribbon-like, and helical geometry. These supramolecular structures are stabilized by intermolecular hydrogen bonding interaction (N–H⋯N, N–H⋯O, O–H⋯N, O–H⋯O, and C–H⋯O) and π⋯π interaction capability of PyimH ligand. PyimH generally acts as an excellent chelating ligand for a range of metal ions and is also a capable supramolecular glueing agent due to hydrogen bonding and π-stacking ability.
本文综述了2-(2 ' -吡啶基)咪唑(PyimH)作为配位体的作用，以及它通过氢键和π⋯π相互作用作为超分子剂的作用。两个N配位使2-(2′-吡啶基)咪唑成为类似于2,2′-联吡啶的配体。咪唑和吡啶sp 2氮的同向取向使其成为双齿螯合配体。PyimH主要产生离散配位配合物(0D)，但在少数情况下，由于桥接的共配体，如草酸盐、二氰酰胺、三氰甲烷、croconate、硫氰酸盐和异硫氰酸盐，可以观察到一维配位聚合物。这些离散配位单元和共配体桥接的一维配位聚合物进一步扩展到具有线性、锯齿形、阶梯形、带状和螺旋几何形状的高维超分子体系。这些超分子结构通过分子间氢键相互作用(N - h⋯N, N - h⋯O, O - h⋯N, O - h⋯O和C-H⋯O)和PyimH配体的π⋯π相互作用能力来稳定。PyimH通常作为一系列金属离子的优秀螯合配体，由于氢键和π堆积能力，它也是一种功能强大的超分子胶合剂。

Abstract Volatile organic compounds (VOCs) are considered one of the significant contributors to air pollution because they are toxic, difficult to remove, come from a wide range of sources, and can easily cause damage to the environment and human health. There is an urgent need for effective means to reduce their emissions. The current treatment technologies for VOCs include catalytic oxidation, adsorption, condensation, and recovery. Catalytic oxidation technology stands out among the others thanks to its high catalytic efficiency, low energy requirement, and lack of secondary pollution. The difficulty of this technology lies in the development of efficient catalysts. The research on loaded noble metal catalysts and non-noble metal oxide catalysts in this area over the past few years is briefly described in this work. Firstly, the catalytic destruction mechanism of organic volatile compounds is introduced. Secondly, the effects of structural modulation during catalytic oxidation, such as the adjustment of noble metal particle size and morphology, metal doping, and defect engineering, on the conformational relationships are discussed. Finally, the challenges faced by thermal catalytic oxidation for the degradation of VOCs are discussed, and the prospects for its development are presented.

Abstract Breast cancer cells have long been inhibited by polypyridine Ru(II) complexes, which are excellent antitumor agents. Due to their multi-targeting properties, this class of ruthenium complexes has received increasing attention as anticancer drug candidates approach to various cellular targets. The aim of this review is to give information about the ligands that were carefully chosen for ruthenium complexes. There has been a great deal of interest in using ruthenium-based complexes to treat breast cancer. Several species have shown potential as treatment candidates. However, further research is needed to determine how these agents affect the metastatic potential of breast cancer cells. The mechanism of action of Ru-based anticancer candidates NAMI-A and KP1019 during phase I clinical trials has been discussed. This article explains hormone-positive breast cancer and triple-negative breast-cancer treatment by using Ru complexes. Although platinum (Pt-based) anticancer medication is widely used in cancer treatment, a minor improvement has been seen and that is Platinum replaced with Ruthenium for its anticancer properties. We have also highlighted the best effective ruthenium-based complexes in treating T.N.B.C. (triple-negative breast cancer) here in this collection.

Abstract Inorganic metal oxide ZnO in the form of nano particles can change the way diseases are diagnosed and treated. ZnO Nps are selective in targeting cancer cells and due to its nano size can enter into cells and destroy it. Drugs, fluorescent agents (for imaging), targeting agents (to target diseased cells only) etc. be loaded on ZnO Nps to deliver drugs selectively in a controlled manner to specific site. ZnO Nps is non toxic as declared by medical community and hence can replace the inaccuracy and harmful side effects of conventional medicine in bulk form. In this review we have discussed about the preparation and characterization of ZnO Nps. Later part concentrated on applications in various fields including biomedical field.
