“…47.75%) in the range of 480-720 C can be ascribed to the decomposition of coordinated ligand. 44 A horizontal thermal curve was observed above 1100 C, which is due to the formation of the thermally stable product Eu 2 O 3 (30.38%). The amount of the chelated europium(III) ions was determined to be 26.24%, and this value roughly corresponds to a molar ratio of 1 : 1 between L and Eu 3+ .…”

“…The easy modification of their physical properties by varying the metal ions or modifying the ligands makes them a very promising prospect [29]. Andre Duerrbeck et al synthesized supramolecular metallo-networks in a solid state between Eu(III) and a rigid ditopic tridentate terpyridine ligand, and considered that their micron-sized fibers could be used as an efficient optical wave-guide for Eu(III) emission [30].…”

Hydrophilic copolymers containing 2,2′:6′,2″-terpyridine moieties and acrylic acid (AA) units poly (acrylic acid-co-4-(2,2′:6′,2″-terpyridin-4′-yl)styrene) (P(AA-co-TPY)) were synthesized and characterized. Coordinated with different transition metal ions, the dilute aqueous solution of the copolymers exhibited red-shifted UV-vis absorption peaks of π-π* transition from 317 to 340 nm. Further, interacting with iron ions, the copolymer showed new absorption peaks at a longer wavelength region (570 nm) and the absorption intensity enhanced with increase of the ion concentration. When enough ions were added to coordinate with the 2,2′:6′,2″-terpyridine moieties, novel metallo-supramolecular hydrogels were obtained due to the formation of metal coordination bonds between polymer back bones and transition metal ions (Ni2+, Zn2+, Cd2+, Fe2+ and Cu2+), which acted as self-assembly crosslinking structures. The mechanical strength and morphology of the resulting metallo-supramolecular hydrogels have been investigated.

“…Among the various aromatic multidentate ligands, terpyridine and its derivatives, especially carboxylates, have been widely used because the delocalized π-electron system provides a strongly absorbing chromophore and the carboxylate groups interact with the oxophilic lanthanides, 6 although the development is nowhere near satisfactory. [7][8][9][10][11][12][13][14][15] We have also made some attempts in this respect and constructed a series of Ln-based coordination polymers successfully. 16,17 Compared with the ligands reported before, we move away from the ubiquitous use of symmetrical 4′-(4-substituted)-terpyridines and pay more attention to 4′-(2-substituted)-4,2′:6′,4″-terpyridine, which remains largely unexplored.…”

Six families of new lanthanide coordination polymers, [Ln 2 (L) 6 (H 2 O) 2 ] n •3nH 2 O (Ln = Nd (1), Sm (2), Eu (3), Gd (4), Tb (5), Dy (6), Ho (7), Er (8), Yb ( 9 14), Gd (15), Er ( 16)), (HL = 4′-(2-carboxyphenyl)-4,2′:6′,4″-terpyridine, H 2 ox = oxalic acid, H 2 glu = glutaric acid, H 2 adip = adipic acid, H 2 (1,2-bdc) = benzene-1,2-dicarboxylic acid) were synthesized under hydrothermal conditions and characterized by elemental analysis, IR and single crystal X-ray diffraction. Compounds 1-9 are isomorphic 1D chain structures based on binuclear Ln(III) units. Compound 10 is a 1D chain, where L − ligands dangle on two sides of the Pr-ox zigzag chain. Compounds 11 and 12 exhibit distinct 2D-layer structures consisting of Ln 2 (COO) 4 binuclear units. Compound 13 displays an appealing 3D network structure, where the auxiliary ligand H 2 adip plays a significant role in the self-assembly process. Compounds 14-16 present a 1Dchain structure which is extended to a 2D-supramolecular framework by means of weak interactions. The diverse structures further verify the potential of HL ligand in the preparation of coordination polymers with new structures and properties. The effects of auxiliary ligands and coordination modes of HL ligand on the crystal architectures are discussed. The solid-state luminescence and thermal stabilities of compounds 1-16 also were studied. Based on the luminescent properties, we have designed and constructed successfully a series of doped-lanthanide MOF by adjusting the co-doping ratio of Eu(III) and Tb(III) into the same framework as that of 1-9. Interestingly, the luminescent colors of the Eu(III)-doped Tb(III) compounds can be tuned with change of excitation wavelength. Moreover, white-light emission was achieved on excitation at 330 nm.
