Abstract We are now well-positioned to comprehend carcinogenesis at a molecular level in greater detail due to significant technological advancements. Additionally, we are now able to rationally design and develop drug molecules with the ability to either selectively enhance or disrupt important biological processes, maximizing their therapeutic potential. This has heralded a new era in drug design. The heterometallic ruthenium–platinum complexes can be used as anticancer, photodynamic therapy, diabetes treatment, and molecular sensors for thiol-containing peptides due to their multifunctional interactions with nuclear DNA, mitochondrial DNA, RNA, and proteins. Compared to cisplatin and its Ru-based monometallic precursors, a significant number of reported ruthenium–platinum complexes exhibit enhanced cytotoxicity and tumor selectivity. Due to the covalent binding of the cis-PtIICl2 moiety to DNA, photoactive Ru(II)–Pt(II) complexes were designed to prelocalize a photodynamic therapy agent at the site of action. The development of ruthenium–platinum-based heterometallic complexes has recently advanced, opening up new avenues for the development of drugs that are more efficient. Metal complexes’ potential as important cancer therapeutic agents will be the primary focus of this review. The development of ruthenium and platinum-based mono and mixed-metal complexes with therapeutic and biomedical applications are discussed in detail in this article.

Abstract In the recent past the molecular engineering of coordination metal complexes has attracted new interest in the field of nonlinear optics (NLO), which find their applications in optoelectronics and optical data storage technology it is the transition metal along with the organic moieties that induce the control over the optical nonlinearity these properties of the materials not only enhance the intensity but also have a drastic effect on the polarization of incident laser light. This is an important criterion for all-optical switching applications. Coordination metal complexes are a very good target to aim at because of their robustness, physical and chemical stability, and other variable degrees that lead to an increment in NLO responses, most importantly all these properties can be either manipulated or tailored or tunable according to the requirement. Apart from the metal center, these molecules acting as legend must be chromophoric with donor-acceptor nature. In these molecules, the NLO response is intrinsically based on the ‘push-pull’ mechanism of the electrons. Obviously to these molecules, when a metal is in contact, the electronic push-pull mechanism alters rendering the molecule non-symmetric. This review article mainly concentrates on small mononuclear metal complexes for NLO application.

Abstract Photochromic compounds are well known and attract tremendous necessity for their versatile applications in various fields of science. When exposed to light, metal complexes containing potentially photoswitchable azo (–N=N–) and imine (–C=N–) based ligands can be switched between trans (E) and cis (Z) two isomers, as well as energy manipulation and energy level modulation. Then the cis (Z) isomers underwent slow thermal isomerization back to the more stable trans (Z) isomers. The quantum efficiency of metal complexes has been tuned by modifying the ligands’ structures and altering metal substrates. Herein our review encompasses the photochromic behavior of a few conjugated azo-imine (–N=N–C=N–), ligands such as arylazoimidazoles, phenylazopyridine, azobispyridine, arylazopyrozoles, as well as a few non-conjugated azo-imine or Schiff base ligands with their metal complexes.
摘要:光致变色化合物因其在各个科学领域的广泛应用而受到广泛关注。当暴露于光下时，含有潜在可光切换的偶氮(- N=N -)和亚胺(- c =N -)基配体的金属配合物可以在反式(E)和顺式(Z)两个异构体之间切换，以及能量操纵和能级调制。然后顺式(Z)异构体经过缓慢的热异构化反应回到更稳定的反式(Z)异构体。金属配合物的量子效率是通过修饰配体结构和改变金属底物来调节的。本文综述了几种偶氮亚胺(- N=N -c =N -)的光致变色行为，配体如芳唑并咪唑、苯并吡啶、偶氮双吡啶、芳唑并吡唑，以及一些非共轭偶氮亚胺或席夫碱配体及其金属配合物。

Abstract In most intermetallic europium compounds, the Eu atoms exhibit a divalent oxidation state with a high effective magnetic moment since Eu2+ is isoelectronic with Gd3+. Trivalent intermetallic Eu compounds, in contrast, are extremely scarce and under 20 examples are known to literature. This mini-review summarizes the known binary and ternary examples along with their crystal-chemical peculiarities as well as their magnetic and 151Eu Mössbauer spectroscopic behavior. Additionally, compounds that exhibit valence phase transitions are summarized.

Abstract In the last few decades, transition metal complexes incorporating various azo ligands have drawn much attention. A different group of researchers designed various multidentate azo ligands and explored the coordinating behavior with transition metals of such azo ligands. Transition metal chelates have a wide range of applications in synthetic chemistry. The ligand backbone containing both azo (–N=N–) and azomethine (–CH=N–) or imine (C=N–) groups have gained remarkable impetus for research in organometallic chemistry. The transition metal chelates incorporating azo-azomethine ligands are plentiful owing to their variant features with multiple coordination sites of the polydentate ligands. The versatile geometry of metal chelates and their potential applications in various fields of life has bestowed a high platform in coordination chemistry. The current review covers the synthetic strategies and coordination behavior of a potential azo ligand named 2,2′-bis(diamino)azobenzene and its related ligands with metal complexes of d-block elements. We have also scrutinized the applications of these ligands in synthetic chemistry and the azo-imine character of ligands in metal complexes.

Abstract Volatile organic compounds (VOCs) are an important class of environmental pollutants, and there is much interest in China to eliminate such pollutants. Noble metal catalysts have long been a family of catalysts with high efficiency and good low-temperature catalytic activity. As a representative of the noble metals, Pt has been widely used. This paper reviews the research trend of Pt-based catalysts for the catalytic oxidation of VOCs, and it compares several important components of Pt-based catalysts. The size of Pt particles, supported carriers, and reaction mechanism are reviewed. Toluene in VOCs is the main research subject. The activity, stability, water resistance, and selectivity of a series of Pt-based catalysts are summarized.

Abstract Detection of different chemical moieties especially trace metals is important for humans as well as water safety. In this review, different detectors synthesized by the combination of different ligands with luminescent europium complexes were discussed for the separation of metals and chemical moieties in aqueous media. These detectors displayed high sensitivity and selectivity. The limit-of-detection values were very low indicating that these detectors are best suitable for the sensing of chemical moieties and trace metals. These detectors’ luminescent changes could be noticed with the naked eye.
