Coordination-Directed Self-Assembly of Functional Polynuclear Lanthanide Supramolecular Architectures

Lanthanide supramolecular chemistry is a fast growing and intriguing research field due to the unique photophysical, magnetic, and coordination properties of lanthanide ions (LnIII). Compared with the intensively investigated mononuclear Ln-complexes, polymetallic lanthanide supramolecular assemblies offer more structural superiority and functional advantages. In recent decades, significant progress has been made in polynuclear lanthanide supramolecules, varying from structural evolution to luminescent and magnetic functional materials. This review summarizes the design principles in ligand-induced coordination-driven self-assembly of polynuclear Ln-structures and intends to offer guidance for the construction of more elegant Ln-based architectures and optimization of their functional performances. Design principles concerning the water solubility and chirality of the lanthanide-organic assemblies that are vital in extending their applications are emphasized. The strategies for improving the luminescent properties and the applications in up-conversion, host–guest chemistry, luminescent sensing, and catalysis have been summarized. Magnetic materials based on supramolecular assembled lanthanide architectures are given in an individual section and are classified based on their structural features. Challenges remaining and perspective directions in this field are also briefly discussed.

“…The Claisen condensation is known as the main synthetic method for the preparation of fluorinated β-diketones. The most frequently used condensing agents are NaH [31][32][33][34][35] and MeONa [36][37][38][39][40][41][42][43], while LiH [44][45][46][47][48], LDA [49] and Na [50] are less demanded. Ethers (DME, Et2O, THF) are more pre ferred solvents rather than benzene or alcohols.…”

This review summarizes the data on the synthesis of coordination compounds containing two or more different metal ions based on fluorinated β-diketonates. Heterometallic systems are of high interest in terms of their potential use in catalysis, medicine and diagnostics, as well as in the development of effective sensor devices and functional materials. Having a rich history in coordination chemistry, fluorinated β-diketones are well-known ligands generating a wide variety of heterometallic complexes. In this context, we focused on both the synthetic approaches to β-dicarbonyl ligands with additional coordination centers and their possible transformations in complexation reactions. The review describes bi- and polynuclear structures in which β-diketones are the key building blocks in the formation of a heterometallic framework, including the examples of both homo- and heteroleptic complexes.

“…17 Lanthanides exhibit remarkable spectroscopic and electromagnetic properties that make them attractive building blocks; [18][19][20][21] however, their application has been constrained by factors such as variable coordination numbers and low steric requirement. Inspired by the pioneering research conducted by Piguet, 22,23 Bünzli, 24 Gunnlaugsson, 25 Park 26 and others, [27][28][29][30][31][32][33][34][35][36][37][38][39][40] primarily including mononuclear bundles and dinuclear helicates, the field of lanthanide assembly chemistry has witnessed significant advancements. These achievements serve as valuable benchmarks, offering valuable insights and guidance for the future design and synthesis of more intricate and functionalized LOPs.…”
