Zirconium-based metal–organic framework gels for selective luminescence sensing

Abstract

Zr-based MOF nanomaterials are developed via a metal–organic gelation method for rapid and effective luminescence vapour-sensing.

Synthesis and characterizations of YZ-BDC:Eu3+,Tb3+ nanothermometers for luminescence-based temperature sensing

“…Furthermore, absorbance peaks below 900 cm À1 assigned to the out-of-plane C-H bands of the aromatic ring conrmed even more clearly the formation of the zirconium metal-organic frameworks compounds. 20,26 3.2. The thermal stability of the YZ-BDC:Eu 3+ ,Tb 3+ nanothermometers…”

“…These include UiO-66, MOF 804, MIL-140A, Zr-ABDC, etc. 16–21 However, for many applications, especially biomedical applications such as temperature sensing and imaging, the size of Zr-MOF thermometers must be reduced to the nanoscale. 22 One of the most effective solutions to reduce the size of these thermometers is to use an appropriate amount of H 2 BDC and adjust the pH of the zirconium carboxylate precursor solutions, as well as to conduct microwave-assisted hydrothermal reactions.…”

Visible-Light-Driven Production of Solar Fuels Catalyzed by Nanosized Porphyrin-Based Metal–Organic Frameworks and Covalent–Organic Frameworks: A Review

“…Most porphyrinic MOFs are built upon the well-known deprotonated tetrakis­(4-carboxyphenyl)­porphyrin (TCPP 4– ) ligand, either as a free base or in one of its metalated forms (Figure ); the most common node used is the zirconium­(IV) oxide [Zr 6 (μ 3 -O) 4 ] cluster, where a varying number of O-containing ligands (H 2 O, OH – , and RCO 2 – ) complete the coordination sphere. Through solvothermal conditions and various reagent ratios, many different MOFs such as PCN-22, PCN-133, PCN-134, PCN-137, PCN-138, PCN-221, PCN-222 (MOF-545), , PCN-223, ,, PCN-224, , PCN-225, , PCN-226, PCN-600, PCN-900, MOF-525, NU-901, NU-902, NU-1000, TBP-MOF, and Zr-PMOF are accessible (this list is not exhaustive). Other nodes are sporadically found, as shown in Figure .…”

Multifunctional lanthanide MOF luminescent sensor built by structural designing and energy level regulation of a ligand

“…As a new type of organic and inorganic hybrid material, metalorganic frameworks (MOFs) integrate metal ions and organic ligands by coordinated interactions and have been studied in lots of fields, including gas storage and separation, [1][2][3][4][5] heterogeneous catalysis, [6][7][8][9][10] proton conduction, [11][12][13][14][15] luminescence detection, [16][17][18][19][20][21][22] etc. MOFs have a huge specific surface area and dense pore channels that can be designed and controlled.…”
