Preparation and characterization of isostructural lanthanide Eu/Gd/Tb metal-organic framework thin films for luminescent applications

Ultra-thin films of amphiphilic lanthanide complexes: multi-colour emission from molecular monolayers

“…[2][3][4][5][6][7] These characteristics have led to these compounds being used as sensors, 7 imaging agents, 7 lasers, 8 optical displays, 8 and multi-emissive materials. 4,6,9 Multi-emissive materials (in this context materials either made up of multiple Ln 3+ containing molecular species or molecular species containing two or more Ln 3+ ions) [10][11][12][13][14][15][16][17] in particular are high value targets owing to their propensity towards more advanced and complex applications including molecular barcodes, 12 ratiometric sensors, 13 molecular logic gates 18 and white emissive solids. 14,16,19 To translate into functional materials, it is desirable to immobilise Ln 3+ multiemissive species onto surfaces, however only limited examples exist of surface immobilised multi-emissive species.…”

Self-Assembly of Lanthanide-Based Metallogel Nanoplates into Microcubic Blocks as Self-Calibrating Luminescent Methanol Sensors

“…46 Moreover, the characteristic bands at 1634−1385, 1638−1384, and 1636−1395 cm −1 in the three xerogels correspond to the asymmetric and symmetric tensile vibration peaks of the coordinated COO − , respectively. 47,48 Therefore, the above FT-IR spectra changes clearly show the coordination of metal and ligand during the formation of metallogels. 49−51 In addition, most of the main vibration peaks shift to lower wavenumbers after gelation, indicating hydrogen bond formation.…”

“…3b), respectively. Moreover, the additional photoelectron peaks at 1276.49 eV and 1242.16 eV in the Tb 3d spectrum of Tb-UiO-66 were assigned to Tb 3d transitions 36 (Fig. 3c).…”
