In this study, we utilize a mesoporous Silicate-1 zeolite catalyst incorporating encapsulated PtNi clusters to systematically investigate the structural characteristic and electronic properties, and further correlated them with the catalytic performance for the room-temperature CO oxidation. Our findings reveal that the incorporation of Ni atoms significantly enhances oxygen adsorption and dissociation, thereby mitigating CO poisoning effects commonly observed in pure Pt clusters at low temperatures. This synergistic effect enables complete CO conversion at near-ambient temperatures (~30°C). These insights elucidate the fundamental mechanisms underlying the synergistic effects of alloy clusters in confined environments and highlight the potential for precise engineering of alloy cluster functionality for targeted catalytic applications.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"36 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dolores Santana, Vicente Marchan, Jose Ruiz","doi":"10.1039/d5qi00858a","DOIUrl":"https://doi.org/10.1039/d5qi00858a","url":null,"abstract":"The coumarin scaffold exhibits remarkable chemical adaptability, allowing modifications at nearly every position. This versatility enables precise customization of its photophysical, photochemical, physicochemical, and biological properties both for bioimaging and therapeutic applications. Transition metal complexes with photofunctional capabilities have also garnered significant attention as light-activated drugs due to their diverse and well-established photophysical and photochemical characteristics, facilitating numerous biomedical applications. In this context, both coumarin derivatives and transition metal complexes have been extensively employed in light-induced therapies, including photodynamic therapy (PDT) for cancer treatment. PDT, a clinically approved treatment modality for various medical conditions, relies on the use of light-activated drugs, known as photosensitizers (PSs), which are activated by specific wavelengths of light to generate cytotoxic reactive oxygen species (ROS) capable of eliminating cancer cells. This review offers a comprehensive analysis of the strategic development of advanced metal-based PSs incorporating coumarin derivatives, emphasizing the unique photophysical, photochemical and photobiological properties provided by the coumarin scaffold. The discussion is systematically divided into two major sections based on the integration approach of the coumarin within the metal complexes: 1. Metal complexes with coumarin attached via non-conjugated linkers. This section details cases where coumarin is indirectly linked to the metal center. 2. Metal complexes with coumarin integrated into ligands. This section explores systems where the coumarin is directly involved in the metal coordination sphere, either through direct bonding or via conjugated linkers that enhance electronic interactions with the metal center. This structured approach facilitates an in-depth comparison and analysis of design strategies for these innovative therapeutic agents. Special attention is given to metal-COUPY conjugates, featuring cyclometalated Ir(III) or Ru(II) complexes, and Ru(II)-COUBPY complexes, where the coumarin scaffolds are incorporated into Ru(II) polypyridyl complexes through a bipyridine ligand.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"13 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While these classes of compounds have been widely studied separately or combined in derivatives that display a dual therapeutic effect, herein, a novel study on the conjugation of Ru(II) and Pt(II) fragments into a single bimetallic conjugate is proposed. It is assumed that this molecular design could undergo an intramolecular electron transfer from the Ru(II) moiety to the Pt(II) moiety upon irradiation to produce a highly efficient excited state. Capitalizing on the presence of both metals, the bimetallic conjugate was found to generate singlet oxygen with an outstanding efficiency in comparison to its individual components. To enhance the pharmacological profile, the bimetallic complex was encapsulated into polymeric nanoparticles. The nanoparticles were demonstrated to eradicate human breast adenocarcinoma monolayer cells as well as multicellular tumor spheroids upon light irradiation at nanomolar concentrations.
