“…[ 50–52,136 ] Moreover, the luminescence of RE ions have advantages of narrow bandwidth, long decay time, high quantum yield, large Stokes shifts, and high photostability, which is due to the shielded 4f electrons by outer electrons. [ 47,55 ] As shown in Table 1 , the luminescence of 2D RE materials is focused on RE doping types and RE hybrids, where RE can endow the 2D materials with excellent luminescence features.

“…[ 37,41–46 ] Briefly, RE ions have two ground‐state electron configurations including [Xe]4f n and [Xe]4f n −1 5d 1 . [ 41,47–49 ] The 4f electrons in 4f n configuration are localized core‐like and have a strong correlationship with n . [ 50–55 ] Localized 4f transitions including the f–d interconfigurational and f–f intraconfigurational transitions endow RE with atomic‐like optical transitions, which can be observed as sharp and various absorption or luminescence bands.…”

2D rare earth (RE) materials have received considerable attention in recent years due to the fascinating luminescence, magnetism, and electric properties originated from RE associated with sharp and various emission peaks, intrinsic 2D ferromagnetism, and incommensurate charge density wave. These materials might open up a new prospect in next‐generation lighting, magnetic devices, and phototransistors. Herein, a comprehensive review of 2D RE materials is presented, focusing on their recent progresses. First, the crystal structures of 2D RE materials are discussed. Then, typical synthesis methods such as mechanical exfoliation, molecular beam epitaxy, pulsed laser deposition, and chemical vapor deposition are introduced. Furthermore, various properties in luminescence, magnetism, and electronics are summarized. The recently reported RE‐based 2D novel photodetectors are outlined as three constructions: MoS2/RE, graphene/RE, and perovskite/RE, which show promising applications for both narrow and broad band detection arised from the special absorption windows of different RE elements. Finally, the conclusions and outlook of this area are proposed, such as exploring novel 2D RE compounds, improving stability, and broadening applications.

“…In the last decade, the interest in lanthanide-based MOFs, LnOFs hereafter, is rising due to their versatilities in areas such as luminescence [6,7], gas adsorption [8][9][10][11], optical storage [12,13], and magnetism [14]. The problem lies on the fact that lanthanide elements have very high and variable coordination numbers, which brings us to the issue that the coordination geometries and the LnOF topologies are difficult to control [15]. Instead, once a dominant architecture is achieved and the factors affecting the structural variability are isolated [16][17][18], it allows obtaining an isostructural family of lanthanide-based materials in which a comparative analysis of a specific property may be accomplished.…”

Exploring the Slow Magnetic Relaxation of a Family of Photoluminescent 3D Lanthanide–Organic Frameworks Based on Dicarboxylate Ligands

et al. 2021

A family of metal–organic frameworks with general formula {[Nd2(ant)2((NH2)2-bdc)(DMF)4]·2DMF}n (1) and {[Ln2(ant)2((NH2)2-bdc)(DMF)4]·2DMF·2H2O}n (Ln = Tb (2), Ho (3), and Er (4)) has been obtained from reactions between 9,10-anthracenedicarboxylic (H2ant) and 2,5-diaminoterephthalic ((NH2)2-H2bdc) acids, and lanthanide ions in dimethylformamide (DMF). These lanthanide–organic frameworks (LnOFs) have been characterized, and their crystal structures have been elucidated by single crystal and powder X-ray diffraction methods (on the basis of a comparative refinement with similar structures), respectively for 1 and 2–4. All LnOFs present three-dimensional structures composed of dinuclear [Ln2(µ-CO2)4] entities linked through both carboxylate ligands that yield open frameworks in which DMF and water molecules are located in the channels. Magnetic studies of these LnOFs have revealed slow relaxation of the magnetization for the Nd-based counterpart. The compounds also acknowledge relevant photoluminescence (PL) emissions in the visible (for the Tb-based homologue) and near-infrared (for the Nd- and Er-based compounds) regions. The strong green emission yielded by compound 2 at room temperature allows its study for photoluminescence (PL) sensing of various solvent molecules, finding a particular discrimination for acetone.

“…[13][14][15][16] Rare-earth (RE) metals, which include scandium, yttrium and the fifteen lanthanides, have been used to synthesize a diverse library of MOFs, including many with unique structures and properties driven by the high coordination numbers and geometries of RE-metals. [17][18][19][20] Like other classes of MOFs, RE-MOFs have been reported with several different secondary building units (SBUs), including inorganic nodes that are metal ions, 21,22 chains, [23][24][25] or clusters. 5,[26][27][28][29] In 2013, Eddaoudi et al showed that the use of fluorinated modulators, such as 2-fluorobenzoic acid, favors the formation of RE-cluster nodes, instead of the ion or chain nodes that tend to preferentially form in the presence of carboxylic acid linkers.…”

The design and synthesis of new metal–organic frameworks (MOFs) is important from both a fundamental and application standpoint. In this work, a novel, highly‐connected rare‐earth (RE) MOF with shp topology is reported, named RE‐CU‐10 (RE = rare‐earth, CU = Concordia University), comprised of nonanuclear RE(III)‐cluster nodes and tetratopic pyrene‐based linkers. This represents the first time that the 1,3,6,8‐tetrakis(p‐benzoic acid)pyrene (H4TBAPy) linker is integrated in the shp topology. Y‐CU‐10 was explored as a heterogeneous photocatalyst for the selective oxidation and detoxification of a sulfur mustard simulant, 2‐chloroethyl ethyl sulfide (2‐CEES), showing a halflife for conversion to the less toxic 2‐chloroethyl ethyl sulfoxide (2‐CEESO) of 6.0 min.<br>
