“…In this system, the organic ligand acts as a photoantenna that can transfer, after excitation, energy from the ligand excited triplet state to the excited state of the lanthanide. Then, the relaxation of the energy from the excited level to the fundamental level of the Ln ion produces a long (μs to ms) and sharp luminescence emission that is sparsely affected by the surrounding environment. − Lanthanide luminescence was used in several applications, − especially to generate emitting materials by immobilizing monolayer or polylayers of Ln complexes on several substrates. − In contemporary chemistry, the functionalization of surfaces with hierarchical mono- and polylayers presents a great interest and is used in several technological applications. − …”

Lanthanide (Ln) based luminescent materials are experiencing an increasing interest in their applications in several fields. In this study, we report a series of new lanthanide-oligomeric brush films, supported on quartz substrates and prepared using a layer-by-layer method (LbL). Oligomeric brush films are composed of small oligomers from our previously reported coordination polymers [x-EuL] and [x-TbL] (with x = 1, 3, and 5 generations of Ln complexes), which are grown perpendicularly from a carboxylate self-assembled monolayer. Oligomers composed of our previously described helical lanthanide complex LnL (Ln: Eu and Tb) as a luminescent moiety and benzene-1,4-dicarboxylate acid (bdc) used as a linker. Mixed films having the fifth-generation Ln complexes composed of equimolar mixture of Eu and Tb ions were prepared. Oligomeric brush films are highly transparent and exhibited a colored emission under UV irradiation. Pure Ln (Eu or Tb) films showed a strong luminescence from the Ln ions. Their luminescent properties depended on the number of lanthanide layers in the films composed of the first to third generations of lanthanide complexes. Then, the increase of the complex layers induced no difference in the luminescent properties. An energy transfer from Tb to Eu ions in the mixed films indicated a short distance between lanthanide ions of a fifth layer. The structural analysis together with the observed luminescent properties and some previous studies allowed to clarify the disposition of the oligomers in the films.

Incorporating metal clusters within the skeleton of the organic polymers through a click reaction cannot only effectively prepare cluster–polymer composites, but also effectively avoid the cluster aggregation. Herein, an azide‐containing lanthanide–titanium oxo cluster of Eu8Ti10‐N3 (Eu8Ti10‐N3=[Eu8Ti10(μ3‐O)14(H2O)4(OAc)2(tbba)30(paza)4(THF)2]⋅4 THF⋅8 H2O (1), Htbba=4‐tert‐butylbenzoic acid, Hpaza=4‐azidobenzoate, HOAc=acetic acid, THF=tetrahydrofuran) through an in situ solvothermal reaction of 4‐azidobenzoic acid and 4‐tert‐butylbenzoic acid. Reaction of 1 with PEG (PEG=methoxypoly(ethyleneglycol)alkyne, 2000 g mol−1) through CuI‐catalyzed click chemistry generates a lanthanide–polymer composite of Eu8Ti10‐N3@PEG (2). Investigation with IR, 1H NMR and ICP‐OES of 2 indicates that the structural integrity of 1 is maintained in 2. Study of the luminescent properties of 1 and 2 reveals that the quantum yield of 1 itself basically remains unchanged in 2. Significantly, the formation of 2 cannot only effectively prevent the cluster 1 from aggregation, but also greatly enhance its solubility and adhesion to the substrate. Owing to the solubility and adhesion of luminescent materials being the key to their practical application, present work is thus of great significance for the development of metal cluster–polymer composite luminescent materials.
