“…This coordination motif is well-established and entry into higherdimensionality architectures is typically accomplished by introducing donor groups in the 4′-position. In addition to the widespread use of pyridinyl [5][6][7] and carboxylate [8][9][10][11][12][13] functionalities, sulfonate donors have also been used to access 3D frameworks. 14 3D-networks utilizing only the two pendant donors of the 4,2′:6′,4″-tpy domain are relatively rare, although the reaction of 4′-(pyridin-2-yl)-4,2′:6′,4″-tpy and CoĲNCS) 2 gives a 3D structure in which the pyridinyl substituent is not coordinated.…”

“…We have already reported a series of d-block coordination polymers grounded on it, as well as their luminescent, magnetic and thermal properties. 18,19 To optimize our research system and make the best of its advantages, HL was employed continuously to construct Ln-based CPs with previously undiscovered frameworks and properties. Herein, we report the syntheses, crystal structures, luminescent properties and thermal stabilities of compounds 1- 16.…”

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.

Design, synthesis, and applications of metal–organic frameworks (MOFs) are among the most salient fields of research in modern inorganic and materials chemistry. As the structure and physical properties of MOFs are mostly dependent on the organic linkers or ligands, the choice of ligand system is of utmost importance in the design of MOFs. One such crucial organic linker/ligand is terpyridine (tpy), which can adopt various coordination modes to generate an enormous number of metal–organic frameworks. These frameworks generally carry physicochemical characteristics induced by the π‐electron‐rich (basically N‐electron‐rich moiety) terpyridines. In this minireview, the construction of 3D MOFs associated with symmetrical terpyridines is discussed. These ligands can be easily derivatized at the lateral phenyl (4′‐phenyl) position and incorporate additional organic functionalities. These functionalities lead to some different binding modes and form higher dimensional (3D) frameworks. Therefore, these 3D MOFs can carry multiple features along with the characteristics of terpyridines. Some properties of these MOFs, like photophysical, chemical selectivity, photocatalytic degradation, proton conductivity, and magnetism, etc. have also been discussed and correlated with their frameworks.
