Summary: Upconversion is a promising anti-Stokes-like optical process with potential applications in diverse fields. However, current known mechanisms for upconversion are mainly based on direct energy transfer between metal ions, which limits the design and tunability of the structures and properties. By synthesizing lanthanide-organic complexes with assembly induced excited-multimer states, we demonstrate a new strategy for designing upconversion materials that is crucial for exploiting the photofunctions of multicomponent lanthanide-organic complexes.

Summary: A series of tris-dipicolinate europium complexes with different complexes were prepared and their photophysical properties in the solid state were studied. It was found that second sphere water molecules played a crucial role, with the non-radiative deactivation constant varying significantly depending on the number of interstitial water molecules and their distance to the europium emitting center. The complex (NBu4)3[Eu(DPA)3], which had the most lipophilic cation, showed excellent solubility and remarkable photophysical properties in aprotic solvents.

Summary: By reacting the trigonal lanthanide complexes LnL with 1-octadecylamine, the aldehyde groups are transformed to 1-octadecylimine groups, forming the novel aliphatic lanthanide complexes LnL(18) (Ln = Yb, Lu). The crystal structure of YbL18 shows that the reaction leads to subtle changes in the coordination sphere of Yb(iii), while the octadecyl chains direct crystal packing into lipophilic arrays. The static magnetic properties and energy level splitting of YbL18 are compared to those of the non-derivatised complex YbL.

Summary: Luminescent thermometry enables remote temperature detection and has great potential in future technological applications. We demonstrate for the first time that luminescence thermometry can be combined with a complementary temperature readout related to a different property. By taking advantage of the temperature dependence of magnetic and luminescence features in Single-Molecule Magnets (SMM), we develop original dual magneto-optical molecular thermometers that offer a 10-fold improvement in relative thermal sensitivity over the whole temperature range.

Summary: An effective strategy for tunable room-temperature multicolor to white-light emission was achieved by mixing different lanthanide ions (Sm3+, Tb3+, and Ce3+) in three-dimensional coordination frameworks based on hexacyanidoruthenate(II) metalloligands. By forming blue RuII emission, red SmIII emission, and green TbIII emission in the Ln-NC-Ru linkages, the emission characteristics for different lanthanide ions were successfully adjusted.

Summary: The utilization of azobenzene-based photoisomerization has been explored to control the morphology of supramolecular assemblies and regulate biological processes. However, the design of azobenzene-involved nanoconstructs with switchable photoluminescence remains challenging. In this study, a multicomponent nanosystem derived from azobenzene is reported and its function as a supramolecular lanthanide photoswitch is investigated. The mutual cooperation of host-guest complexation and metal-ligand coordination enables the photoswitchable luminescence abilities of azobenzenes, which holds promise for the development of advanced light-responsive smart materials.

Summary: Several new Ln(2+) diaza-crown complexes were synthesized by direct synthesis of LnI(2) with 1,10-dibenzyl-1,10-diaza-18-crown-6 in organic media under air-free conditions. The coordination of the ligand with Ln(2+) caused distortion of the diaza-crown structure and resulted in closer interactions between the oxygen donors in the crown ether and the Ln(2+) center. The formation of different structures led to the discovery of three isostructural 8-coordinate complexes and two separate complexes.

Summary: We present the design of novel composite films consisting of cyano-bridged coordination polymers Fe-II[Fe-II(CN)(5)(NO)] or Ag-2(I)[Fe-II(CN)(5)(NO)] grown into a chitosan matrix, which exhibit a slow release of NO radicals under white light irradiation. The characterisation methods confirm that these composites comprise of approximately 50 wt% cyano-bridged coordination polymer microcrystalline particles embedded in chitosan films. Irradiation with white light for 7 days results in a NO radical delivery of 6.5% and 10.6% for {Fe[Fe(CN)(5)(NO)]}(0.55)@C6H11NO4 and {Ag-2[Fe(CN)(5)(NO)]}(0.28)@C6H11NO4, respectively. The rearrangement of cyano-bridged coordination compounds after the departure of NO leads to the formation of Prussian blue or silver Prussian blue analogues, effectively preventing the undesired release of cyanide as a side effect.

Summary: Glasses with tunable properties are versatile materials for optical technologies. To design new optical glasses, understanding the correlation between their chemical composition and physical properties is crucial. We demonstrate the feasibility of using fluoride phosphate glasses co-doped with Pr3+ and Yb3+ ions for temperature sensing. These glasses have high stability and act as luminescent thermometers without the need for recurring calibration. They exhibit competitive thermal sensitivity and uncertainty, making them promising for cost-effective and accurate temperature probes, advancing photonic technologies.

Summary: It is generally known that the emission intensity of trivalent lanthanide ions (Ln(3+)) increases on cooling, but recent studies have shown that the intensity of Eu3+ photoluminescence decreases on cooling. In this study, the mechanism underlying this anomalous behaviour was investigated using experimental and theoretical approaches. It was found that off-resonance excitation enhanced the Eu3+ emissions with increasing temperature, and the temperature dependence of the emission intensity could be tuned by varying the bandpass of the excitation source.

Summary: Choosing a suitable host matrix for temperature sensing in biomedical applications requires low cytotoxicity, easy synthesis, and the ability to be doped with light-emitting ions. Indium-based halide double perovskites, namely Cs2AgIn0.9Bi0.1Cl6, Cs2Ag0.6Na0.4InCl6, and Cs2Ag0.6Na0.4In0.9Bi0.1Cl6, were selected as host materials to develop lanthanide-based primary thermometers due to their low phonon energy and ease of synthesis. These perovskite samples demonstrated excellent thermal stability and were able to withstand temperatures as high as 500 degrees C. A temperature-dependent green emission of Er3+ was observed in the co-doped samples, exhibiting a relative thermal sensitivity of 1.3% K-1 and an uncertainty in temperature values of 0.3 K. Incorporating these perovskites into L2929 cells resulted in high cell viability, highlighting the advantages of using low-cytotoxicity materials for biological applications.

Summary: The generation of temperature gradients on nanoparticles heated externally by a magnetic field is crucial in magnetic hyperthermia therapy. However, the low heating power of magnetic nanoparticles limits the technique's implementation. This paper reports the real-time measurement of local temperature on gamma-Fe2O3 magnetic nanoheaters, showing that even within health safety limits, local temperature increments are sufficient to cause cell death, demonstrating the feasibility of local hyperthermia.
