Current small-molecule drugs suffer from rapid metabolism and poor organ targeting, limiting their effectiveness in both preventive and long-term exposure scenarios. Nano decorporation agents, despite their prolonged <i>in vivo</i> retention due to nanoscale size and physico-chemical properties, encounter limitations such as restricted long channels and mismatched coordination geometry of chelating sites, which impede rapid and selective uranyl binding under physiological conditions. This study employs discrete metal-organic polyhedra (MOPs) to achieve a dense grafting and flexible arrangement of carboxylic acid chains, aiming to attain collaborative coordination of uranyl ions on the faces of tetrahedral structures. These MOPs selectively capture uranyl at low concentrations <i>in vitro</i> and show superior <i>in vivo</i> removal efficiency compared to clinical drugs and currently reported nano agents in both prophylactic and delayed treatments, where higher grafting density of carboxyl chains leads to greater decorporation efficiency.

However, the relevant study has been frequently obstructed by the large lattice mismatch among different components and their differing crystal growth preferences. In this study, ultrathin bronze-phase TiO₂ nanosheets (TB NSs) were grown epitaxially onto anatase TiO₂ nanobelts (AT NBs) with their basal planes parallel to the latter’s stretching direction, deriving the epitaxial AT-TB hetero-phase architectures (HPAs). Noticeably, the epitaxial interface helps to minimize the scattering and energy quenching of transferred charge carriers. Moreover, the internal electric field (IEF) of AT-TB HPAs can be strengthened by amplifying the Fermi level gap between AT and TB via oxygen vacancy engineering, which contributes to driving Z-scheme charge transmission effectively. When tested for gas-solid photocatalytic CO₂ conversion, AT-TB epitaxial HPAs exhibited a much superior activity than individual AT NBs and TB NSs, as well as TB-TB epitaxial hierarchitectures without phase-junction. Additionally, the photocatalytic capability of AT-TB HPAs was further notably promoted via site-specific Pd photo-deposition, achieving the CO and CH₄ evolution rates of 48.53 and 16.41 µmol g⁻¹ h⁻¹, outperforming that of many TiO₂-based photocatalysts reported before.

Owing to their distinct topologies, these MOFs enable the selective axial coordination of varying amounts of 4,4′-dipyridylamine (dipya) linkers between neighboring Fe-porphyrin pairs, resulting in Fe centers with different coordination numbers.

These features enable diverse applications in optoelectronics, biological imaging, information encryption, and anti-counterfeiting technologies. However, no review has comprehensively summarized the advances in this field. This review begins by outlining the fundamental mechanisms underlying RTP, with emphasis on intersystem crossing, triplet-state stabilization, and suppression of nonradiative decay pathways, followed by molecular design strategies for achieving efficient and long-lived RTP, particularly those involving aggregation modulation. Next, recent advances are surveyed across various material platforms, including single- and multi-component small molecules, dendrimers, polymers, supramolecular assemblies, and organic porous frameworks, in both crystalline and amorphous forms. Moreover, emerging multifunctional systems, such as clusterization-triggered phosphorescence, circularly polarized phosphorescence, and stimuli-responsive materials, are highlighted. Third, representative applications in anti-counterfeiting, sensing, bioimaging, biotherapy, and optoelectronic devices are critically examined to demonstrate the potential of RTP materials in next-generation smart systems. Finally, key challenges are addressed, including the trade-off between quantum yield and lifetime, oxygen quenching in biological environments, and the need for mechanistic insight via advanced spectroscopic and theoretical methods. In addition, future directions are proposed, such as developing color-tunable near-infrared RTP for deep-tissue imaging and integrating RTP into multifunctional device platforms.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":772,"journal":{"name":"Science China Chemistry","volume":"69 8","pages":"3929 - 4150"},"PeriodicalIF":9.8,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11426-025-3385-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These approaches aim to precisely tailor the catalyst’s microstructures and reaction interfaces, turning potentially detrimental conditions into drivers for sustained or even improved long-term performance.
