• • Terpyridine-lanthanide coordination polymers achieve tunable dimensionality (1D chains to 3D frameworks) via dual-ligand strategies, with Ln-thiophene-2,5-dicarboxylic acid-terpyridine systems demonstrating precise control over pore size and surface area, critical for selective radionuclide sequestration (e.g., UO2²⁺ uptake capacities exceeding 300 mg/g) and detection in nuclear waste streams.
• • Electrospun europium-chain@polymer nanofiber films enable visual detection of Fe³⁺ ions at concentrations as low as 10⁻⁶ M, with a rapid response time (<5 s) and reversible on/off switching, offering a low-cost, field-deployable sensor platform for environmental monitoring and clinical iron overload diagnostics.
• • White-light-emitting LnMOFs with Eu³⁺ doping achieve CIE coordinates (0.33, 0.33) and quantum yields up to 45%, while mixed-ligand ratiometric thermometers exhibit sensitivity >1% K⁻¹ in the physiological range (25–45 °C), enabling non-invasive thermal imaging and localized hyperthermia control.
• • Self-healing metallo-supramolecular polymers based on lanthanide-terpyridine interactions show luminescence off/on switching with fatigue resistance over 100 cycles and healing efficiency >90% at 60 °C, addressing the durability bottleneck in flexible optoelectronic devices and soft robotics.
