“…In the last two decades, there was a growing interest for lanthanide-based coordination polymers because of their fascinating crystal structures [1][2][3][4] as well as their interesting porosity, [5][6][7][8] magnetic [9][10][11] and optical properties. [12][13][14][15] Because of their unique optical properties lanthanide-based coordination polymers can be suitable for potential applications in various fields such as lighting and display, [14,[16][17] chemical sensing, [18] fight against counterfeiting [19][20][21] or thermometric probes, [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] for examples.…”

Reactions in water of lanthanide chlorides with the sodium salt of 1,4-carboxyphenylboronic acid lead to two series of isostructural compounds with respective general chemical formulas [Ln(cpb)3(H2O)2]∞ for Ln = La or Ce and [Ln(cpbOH)(H2O)2·(cpb)]∞ for Ln = Pr–Lu (except Pm) plus Y. Heterolanthanide coordination polymers that are isostructural to the second series have been synthesized, and their photophysical properties have been studied. This study evidences that it is possible to design multiemissive lanthanide-based coordination polymers that could find their application as multigauge luminescent thermometric probes.

“…For some years, our group has studied in detail hetero‐polynuclear lanthanide‐based terephthalate coordination polymers 16. 22, 27–30 This system comprises several families of coordination polymers. One of these series is constituted by isostructural compounds with the general chemical formula [Ln 2−2 x Ln′ 2 x (bdc) 3 ⋅ 4 H 2 O] ∞ with 0≤ x ≤1, where Ln and Ln′ denote a lanthanide ion within the series from La 3+ to Yb 3+ (except Pm 3+ ) or Y 3+ , and bdc 2− denotes the terephthalate ion (1,4‐benzene‐dicarboxylate).…”

Nine cyclometalated ruthenium complexes with a redox-active diphenylamine unit in the para position to the RuC bond were prepared. MeO, Me, and Cl substituents on the diphenylamine unit and three types of auxiliary ligands-bis(N-methylbenzimidazolyl)pyridine (Mebip), 2,2':6',2''-terpyridine (tpy), and trimethyl-4,4',4''-tricarboxylate-2,2':6',2''-terpyridine (Me3 tctpy)--were used to vary the electronic properties of these complexes. The derivative with an MeO-substituted amine unit and Me3 tctpy ligand was studied by single-crystal X-ray analysis. All complexes display two well-separated redox waves in the potential region of +0.1 to +1.0 V versus Ag/AgCl, and the potential splitting ranges from 360 to 510 mV. Spectroelectrochemical measurements show that these complexes display electrochromism at low potentials and intense near-infrared (NIR) absorptions. In the one-electron oxidized form, the complex with the Cl-substituted amine unit and Mebip ligand shows a moderate ligand-to-metal charge transfer at 800 nm. The other eight complexes show asymmetric, narrow, and intense intervalence charge-transfer transitions in the NIR region, which are independent of the polarity of the solvent. The Mebip-containing complexes display rhombic or broad isotropic EPR signals, whereas the other seven complexes show relatively narrow isotropic EPR signals. In addition, DFT and time-dependent DFT studies were performed to gain insights into the spin distributions and NIR absorptions.

“…This series of isostructural compounds has been chosen because its 3D crystal structure ( Figure 10) is very compact and stable 67 and because luminescent properties of molecular alloys based on terephthalate have been extensively studied. [68][69][70][71][72][73][74][75][76] Emission spectra as well as luminescence lifetimes of Eu 3+ and Tb 3+ ions have been measured for both compounds at room-temperature ( Figure 11 Additionally, luminance has been measured for both samples ( Figure S6). Core-shell sample luminance is 90(1) cd.m -2 while that of the molecular alloy sample is only 22(1) cd.m -2 .…”

Microcrystalline Core–Shell Lanthanide-Based Coordination Polymers for Unprecedented Luminescent Properties

Microcrystalline core–shell powders of lanthanide-based coordination polymers with general chemical formula ([Ln(cpbOH)]∞)1–x @([Ln′(cpbOH)]∞) x with Hcpb = 1,4-carboxyphenylboronic acid have been synthesized and structurally characterized. Their luminescent properties have been studied. They are drastically different from those of heterolanthanide coordination polymers, also called “molecular alloys”, that present the same crystal structure and chemical composition. Study of the photophysical properties of core–shell lanthanide-based coordination polymers reveals that it is possible to control efficiently the intermetallic energy transfers between lanthanide ions. Furthermore, multiemissive compounds, under unique irradiation, in both visible and infrared regions are easily feasible. Core–shell microstructured lanthanide-based coordination polymers have also been prepared with terephthalic (H2bdc) and trimesic (H3tma) acids as ligands for evidencing that lanthanide-ion-based coordination compounds are excellent candidates for 3D molecular epitaxial growth.
