“…Actually, the whole process of ET is quite intricate and includes the major four steps as flowing: the first excited step is achieved owing to the Laporte-allowed as well as spin-allowed ligand-centered absorptions under the UV lamp irradiation; second, through nonradiative intersystem crossing (ISC), the energy of a singlet excited state (S 1 ) is transferred to the lower-energy triplet excited state (T 1 ) of HIN; third, the process of intramolecular ET from T 1 to Eu III ions occurs concurrently with the population of excited 4f states of Eu III ; finally, the radiative course experiences with its typical line luminescent (as shown in Figure d). This observation supplies valuable insights into the emission features of lanthanide–aluminum-based cluster-organic frameworks. , …”

The self-assembly of the lanthanide metal−organic frameworks presents a formidable challenge but profound significance. Compared with the metal−organic frameworks based on 4f−3d ions, the chemistry of 4f−3p metal−organic frameworks has not been fully explored so far. In this study, two lanthanide− aluminum-based clusters [Ln 6 Al(IN) Ln = Gd, abbreviated as Gd 6 Al; x = 2.5, Ln = Eu, abbreviated as Eu 6 Al; HIN = isonicotinic acid) have been meticulously designed and obtained by hydrothermal reaction at low pH. The crystallographic study revealed that both Gd 6 Al and Eu 6 Al clusters exhibit an unprecedented sandwiched metal−organic framework holding a highly ordered honeycomb network. To our knowledge, it is the first case of Ln−Al-based cluster-organic frameworks. Furthermore, magnetic investigation of Gd 6 Al manifests a decent magnetic entropy change of −ΔS m max = 28.8 J kg −1 K −1 at 2 K for ΔH = 7.0 T. Significantly, the introduction of Al III ions into the lanthanide metal−organic frameworks displays excellent solid-state luminescent capability with a lifetime of 371.6 μs and quantum yield of 6.64%. The construction and investigation of these two Ln−Al clusters represent great progress in the 4f−3p metal−organic framework.

“…HRESI-MS and Mechanism of the In Situ Tandem Reaction of Pyraln. The stability and ionization degree of Pyraln in solution were explored using HRESI-MS. 38 In particular, a small number of Pyraln crystals were dissolved in chromatographically pure CH 3 CN and diluted with chromatographically pure CH 3 OH for the HRESI-MS analysis. The results revealed that PyraDy maintained a high stability in the positive-ion mode of HRESI-MS, which mainly showed molecular ion peaks (+1 valence) related to the main framework (Figure 2a).…”

Pinacol lanthanide complexes PyraLn (Ln = Dy and Tb) with the restriction of intramolecular vibration were obtained for the first time via an in situ solvothermal coordination-catalyzed tandem reaction using cheap and simple starting materials, thereby avoiding complex, time-consuming, and expensive conventional organic synthesis strategies. A high-resolution electrospray ionization mass spectrometry (HRESI-MS) analysis confirmed the stability of PyraLn in an organic solution. The formation process of PyraLn was monitored in detail using time-dependent HRESI-MS, which allowed for proposing a mechanism for the formation of pinacol complexes via in situ tandem reactions under one-pot coordination-catalyzed conditions. The PyraLn complexes constructed using a pinacol ligand with a butterfly configuration exhibited distinct aggregation-induced emission (AIE) behavior, with the αAIE value as high as 60.42 according to the AIE titration curve. In addition, the PyraLn complexes in the aggregated state exhibit a rapid photoresponse to various 3d metal ions with low detection limits. These findings provide fast, facile, and high-yield access to dynamic, smart lanthanide complex emissions with bright emission and facilitate the rational construction of molecular machines for artificial intelligence.

“…Lanthanide clusters with nanometer size, beautiful structural connections, and diverse functions have attracted extensive attention 1–5 and have been successfully applied in solid-state luminescence, 6–9 sensing, 10–14 molecular magnetism, 15–21 and bioimaging. 22–24 So far, ligand-controlled hydrolysis and anion-templated methods are still the first choice for the synthesis of lanthanide clusters. 25–29 Under the guidance of above strategies, great progress has been made in the structural synthesis of giant lanthanide clusters.…”
