“…Taking advantage of the open metal sites, the [Eu 2 (69-4H) 2 ] 2− helicate showed selective colorimetric sensing toward omethoate in water via a disassembly mechanism. 140 As discussed in section 2.2, a combination of building blocks with C 2 and C 4 symmetries is required for the construction of quadruple helicates with D 4 symmetry. Self-assembly of Ln ΙΙΙ ions with bidentate ditopic ligands provides a feasible method for the preparation of Ln 2 L 4 helicates.…”

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 less basic G‐series agents have lower affinity for coordinating Eu III . Similarly, omethoate readily displaces the triazole‐pyridine ligands of the bis‐tridentate assembly of Sun, Eu‐ 78 [66] . Decomplexation results in complete quenching of the Eu III ‐centered emission.…”

Inorganic and organic phosphates‐including orthophosphate, nucleotides, and DNA‐are some of the most fundamental anions in cellular biology, regulating numerous processes of both medical and environmental significance. The characteristic long lifetimes of emitting lanthanides, including the brighter europium(III) and terbium(III), make them ideally suited for the development of molecular probes for the detection of phosphates directly in complex aqueous media. Moreover, given their high oxophilicity and the exquisite sensitivity of their quantum yields to their hydration number, those luminescent lanthanides are perfect for the detection of phosphates. Herein we discuss the principles that have guided the recent developments of molecular probes selective for inorganic or organic phosphates and how these lanthanide complexes facilitate the study of numerous biological processes.

Water-stable lanthanide–organic macrocycles from a 1,2,4-triazole-based chelate for enantiomeric excess detection and pesticide sensing

Abstract: Water-stable anionic Ln2L2-type (Ln = LaIII, EuIII) lanthanide-organic macrocycles have been constructed from deprotonation self-assembly of a bis-tridentate ligand consisting of two 2,6-bis-(1,2,4-triazole)-pyridine chelation arms bridged by a dibenzofuran chromophore,...
