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

“…39 and Table S7, the fluorescence lifetime of 5 D 4 of Tb 3+ significantly increased from 404.44 to 963.24 μs (about 2.4 times) and the quantum yield increased from 0.66 to 1.54% (about 2.33 times), which clearly shows that the energy transfers from Tb 3+ to Eu 3+ were hindered. 37,40,69 Moreover, the π−π stacking interaction between the BTC ligand and the methanol molecule was also confirmed in the above spectroscopic change. Although this interaction hardly changes the structure of Eu/Tb-G (Figure S24), it restricts the free rotation of BTC and further changes the energy-transfer efficiency and PL of the Eu/Tb-G system, which was verified with the prolonged fluorescence lifetime and increased quantum yield.…”

RhB‐Embedded Zirconium–Naphthalene‐Based Metal–Organic Framework Composite as a Luminescent Self‐Calibrating Platform for the Selective Detection of Inorganic Ions

“…For ap hotoluminescence property,Z r-MOFs usually present as ingle emission peak because their luminescence is mainly based on the functional ligands or ligand-to-metal chargetransfer-related processes. [26][27][28][29][30] To achieve dual-emitting characteristics and inherit the advantages of Zr-MOFs, combinationsb etween molecular dyes and Zr-MOFst hrough an in situ synthetic encapsulationm ethod are favorable. [22][23][24] In addition, as ingle luminescent re-sponse is often indistinguishable for those analytes with similar structures and chemical and physical properties.…”

“…Some dual-emitting MOFs have exhibited notable progress in sensing temperature, pH, inorganic ions, volatile organic molecules,a nd explosives. [26][27][28][29][30] To achieve dual-emitting characteristics and inherit the advantages of Zr-MOFs, combinationsb etween molecular dyes and Zr-MOFst hrough an in situ synthetic encapsulationm ethod are favorable. [31,32] On the one hand, the fabrication process of the in situ synthesis is effective and straightforward.…”

Three Lanthanide Metal‐Organic Frameworks Based on an Ether‐Decorated Polycarboxylic Acid Linker: Luminescence Modulation, CO2 Capture and Conversion Properties

“…[4][5][6] Therefore, lanthanide MOFs (Ln-MOFs) possessn ot only fascinating structures but also great unique application prospecta s functional materials. [7][8][9][10][11][12][13][14] Another peculity lies in that Ln-MOFs which are constructed from the same ligandsa nd different Ln 3 + ions are commonly isostructural, it provides ag reat chance to prepare doped Ln-MOFsb ym odifyingm olar ratio of Ln 3 + ions, and coming true ad esired colour emission. [15,16] However,t he synthesis and properties of Ln 3 + doped MOFs were not well performed.…”

“…The Ln 3+ metal components are also excellent candidates to construct unique luminescent materials for their large Stokes shift, narrow and intense band emission, high luminescent purity and long luminescent lifetimes . Therefore, lanthanide MOFs (Ln‐MOFs) possess not only fascinating structures but also great unique application prospect as functional materials . Another peculity lies in that Ln‐MOFs which are constructed from the same ligands and different Ln 3+ ions are commonly isostructural, it provides a great chance to prepare doped Ln‐MOFs by modifying molar ratio of Ln 3+ ions, and coming true a desired colour emission .…”
