Summary: A novel lanthanide coordination polymer Eu-dpba composed of Eu(III) ion, low-vibrational frequency hfa, and phosphine oxide ligand with amide groups is reported, showing phase transition behavior. Another lanthanide coordination polymer Eu-dph with alkyl groups is prepared as a reference sample, which does not exhibit phase transition behavior. The smooth surface and unchanged emission quantum yield of Eu-dpba after heat treatment are observed.

Summary: Interactions between lectins and glycoconjugate-terbium(iii) self-assembly complexes are utilized for sensing by enhancing lanthanide luminescence. This glycan-directed sensing method can detect an unlabelled lectin (LecA) associated with pathogen P. aeruginosa in solution, without bactericidal activity. Further development of these probes holds potential as a diagnostic tool.

Summary: A neutral Eu(iii) complex with S,S enantiomer of isoQC3A(3-) ligand was synthesized and spectroscopically investigated, showing similar binding constants and different enhancements of intrinsic quantum yield when compared with a similar complex using bis-anionic ligand bisoQcd(2-). Both complexes can detect citrate at extracellular concentrations up to 500 mu M, even in the presence of other interfering species, making them potential probes for fluorescence analysis of citrate in complex matrices.

Summary: A new luminescent hybrid material based on silica aerogel and a boron-containing coordination compound was successfully created and its physicochemical and spectral-luminescent characteristics were studied. The synthesis of the hybrid material was achieved through a simple scheme, and the mechanisms of the formation of boron-based luminescent complexes were established using in situ luminescent measurements. The incorporation of the boron-containing coordination compound on the surface of the SiO2 aerogel greatly stabilized the structure and enhanced the thermal stability of the hybrid material.

Summary: Two lanthanide complexes supported on MCM48 type silica have been synthesized for creating multi-stimuli responsive materials for anti-counterfeiting applications. This new technology offers a secure way of storing information at different security levels using biocompatible materials. Different luminescent patterns can be revealed and suppressed by external stimuli like chemical agents and heat treatment, providing two levels of security verification and unbreakable encryption.

Summary: In this study, solid materials were prepared by kaolinite functionalization with pyridine 2-carboxylic and pyridine 2,6-dicarboxylic acids, and europium (III) ions were complexed on these solids. The obtained luminescent materials were characterized and evaluated for their potential applications as luminescent sensors. The results showed that the samples functionalized with picolinic and dipicolinic acids exhibited high quantum efficiencies. In the contaminant adsorption tests, the solid material with picolinic acid demonstrated better detection efficiency for chromium (III) in a low concentration range compared to the one with dipicolinic acid.

Summary: Two-dimensional materials have been widely used in various scientific research areas and the concept of constructing photonic devices exclusively from 2D materials has emerged. This review introduces photonic devices solely consisting of 2D materials, including photonic waveguides, lenses, and optical cavities. These devices enable the thinnest possible devices due to their high refractive index, and the unique characteristics of 2D materials may provide intriguing applications.

Summary: The study explores the influence of kinetic energy and irradiation fluence on the generation of luminescent centers in two-dimensional hexagonal boron nitride materials, with a fivefold enhancement observed with increasing fluence. Molecular dynamics simulations clarify the generation mechanism and microscopic nature of these centers, with VNCB and V-B(-) identified as the most likely formed centers. Ab initio calculations of their optical properties show excellent agreement with experimental results, providing insights into the microscopic nature of quantum emitters.

Summary: In this article, a novel microscopy imaging probe based on lanthanide complexes is described. The probe exhibits desirable luminescence properties and cell-penetrating ability for 2P imaging of live cells. By conjugating the lanthanide complexes with cell-penetrating peptides, successful synthesis of the conjugates was achieved and their application in various microscopy imaging techniques was evaluated. The results demonstrate that the probe has proper internalization and cytosolic delivery in cells, while maintaining its original luminescence properties. These findings provide new insights for the development of functional probes for live cell microscopy imaging.
