Application In Synthesis of 2,6-PyridinedimethanolIn 2020 ,《Thermally-Stable Imidazolium Dicationic Ionic Liquids with Pyridine Functional Groups》 was published in ACS Sustainable Chemistry & Engineering. The article was written by Clarke, Coby J.; Bui-Le, Liem; Hallett, Jason P.; Licence, Peter. The article contains the following contents:

Thermally-stable ionic liquids (ILs) have limited structural possibilities and lack coordinating anions or functional groups. Thermal stability effectively incurs a tunability penalty, limiting ionic liquid function to render them as simple heat-stable fluids. In this work, a series of new thermally-stable dicationic ionic liquids with pyridine functional groups, abbreviated [(C8ImC1)2Py][A]2, are presented and compared to nonfunctional geminal dicationic ILs. All ILs have been thermally characterized to understand their elevated temperature stabilities and the processes that lead to their decomposition Importantly, functional [(C8ImC1)2Py][A]2 with noncoordinating anions (i.e., [NTf2]-) have thermal stabilities comparable to those of geminal dicationic ILs, with the added advantage of a functional pyridine moiety. Dissolution of Zn[NTf2]2 in [(C8ImC1)2Py][NTf2]2 is demonstrated, and the resulting solutions are characterized to show their liquid properties, high thermal stabilities, and the coordination of the metal center to the functional group. This is the first example of a thermally-stable functional IL with the potential to reclaim the tunable, task-specific nature of ILs at elevated temperatures Importantly, these properties open new avenues for high-temperature applications of IL by extending their operational ranges; catalysis, metal remediation, and separation-based applications are potential key areas of improvement. A thermally-stable, functional ionic liquid is described that can extend the operating ranges of task-specific ionic liquids In addition to this study using 2,6-Pyridinedimethanol, there are many other studies that have used 2,6-Pyridinedimethanol(cas: 1195-59-1Application In Synthesis of 2,6-Pyridinedimethanol) was used in this study.

Fuentealba, Pablo; Villagra, Danae; Gil, Yolimar; Aguilar-Bolados, Hector; Costa de Santana, Ricardo; Gasparotto, Gisane; Vega, Andres; Manzur, Jorge; Spodine, Evgenia published an article in 2021. The article was titled 《Thermal Dependence of the Luminescent Properties of Mononuclear TbIII Macrocyclic Complexes》, and you may find the article in European Journal of Inorganic Chemistry.Formula: C7H9NO2 The information in the text is summarized as follows:

A family of six terbium(III) complexes with hexaaza macrocyclic ligands, together with the isostructural yttrium(III) species, is reported and the thermal dependence of the photophys. properties of the terbium(III) complexes is analyzed. The coordination number is defined by the anions, nitrate or isothiocyanate, which act as secondary ligands. While complexes with nitrate anions are decacoordinated species, presenting a N6O4 first coordination sphere, complexes derived from isothiocyanate are nonacoordinated with exclusively nitrogen donor atoms. Regarding the optical properties, only the macrocyclic ligands derived from aliphatic amines act as sensitizers for the terbium(III) cations, and the complexes emit in the green region, according to the obtained CIE coordinates. The isothiocyanato ligand plays a detrimental role on the luminescence of the corresponding complexes, since their emission is weaker as compared to that of the nitrato counterparts. The greater achieved thermal sensitivity for one of the studied terbium(III) complexes was 3.2%K-1 at 300 K. The experimental part of the paper was very detailed, including the reaction process of 2,6-Pyridinedimethanol(cas: 1195-59-1Formula: C7H9NO2)

A mol. 623 link (a six crossing, doubly interlocked, [2]catenane with twisted rings) and a 31#31 granny knot (a composite knot made up of two trefoil tangles of the same handedness) were constructed by ring-closing olefin metathesis of an Fe(II)-coordinated 2×2 interwoven grid. The connections were directed by pendant Ph groups to be between proximal ligand ends on the same faces of the grid. The 623 link was separated from the topoisomeric granny knot by recycling size-exclusion chromatog. The identity of each topoisomer was determined by tandem mass spectrometry and the structure of the 623 link confirmed by x-ray crystallog., which revealed two 82-membered macrocycles, each in figure-of-eight conformations, linked through both pairs of loops.

In 2018,European Journal of Inorganic Chemistry included an article by Hastings, Samantha D.; Cagle, Ethan C.; Totsch, Timothy R.; Tyus, Shakyra D.; Gray, Gary M.. Recommanded Product: 1195-59-1. The article was titled 《Comparative Study of Novel Phosphordiamidite and Phosphite Ligands Used in Alkene Hydroformylation; Synthesis, Characterization, Metalation, and Catalytic Evaluation》. The information in the text is summarized as follows:

Three novel ligands have been prepared by the reactions of 1,1′-(chlorophosphinediyl)bis(1H-pyrrole) with either 2-pyridinemethanol or 2,6-pyridinedimethanol or the reaction of 1,1′-biphenyl-2,2′-diyl phosphorochloridite with 2-pyridinemethanol. Measurement of |1JP-Se| values demonstrate that the phosphite donor is less basic than the phosphoramidite donors. Coordination preferences of the ligands in octahedral cis-tetracarbonylmolybdenum(0) and square planar cis-dichloropalladium(II) complexes have been evaluated using multinuclear NMR and x-ray crystallog. Rhodium(I) complexes of the bidentate ligands have been evaluated as catalysts for styrene hydroformylation, and their activities are nearly double those of catalysts containing traditional phosphites. The regioselectivities of the RhI complexes of the bidentate ligands are not significantly different at 80° and 20 atm and are not affected by the addition of a lithium salt. In contrast, changing reaction conditions causes the % n-aldehyde to vary from 15 to 50%. The regioselectivity of the catalyst containing the bidentate phosphoramidite/pyridine ligand was more sensitive to pressure than temperature with both effects being significant.

In 2019,Transition Metal Chemistry (Dordrecht, Netherlands) included an article by Qin, Yutian; Wang, Bowei; Li, Jiayi; Wu, Xingchun; Chen, Ligong. Quality Control of 2,6-Pyridinedimethanol. The article was titled 《Cobalt imine-pyridine-carbonyl complex functionalized metal-organic frameworks as catalysts for alkene epoxidation》. The information in the text is summarized as follows:

Aerobic epoxidation of alkene is a green and economical route to produce epoxides. For such reaction, transition metal complexes exhibit favorable catalytic activity. In this work, NH2-MIL-101, a stable metal-organic framework (MOF) material with large surface area and high pore volume, was functionalized with pyridine-2,6-dicarbaldehyde and Co(NO3)2, to realize the immobilization of Co(II) via imine-pyridine-carbonyl (N,N,O) tridentate ligands bonding to MOF skeleton. The modified materials were applied as heterogeneous catalysts for the aerobic epoxidation of cyclohexene at ambient temperature, and multiple factors were studied to explore their influences on catalytic effects. Under the optimal reaction conditions, satisfactory substrate conversion and epoxide selectivity were reached. In addition, this catalytic system is suitable for a variety of alkene substrates. Furthermore, recycle experiments and IR spectroscopy characterization illustrated that the coordination surroundings of Co are altering smoothly during the reaction process, thus having an impact on the performance of catalyst.

Reference of 2,6-PyridinedimethanolIn 2022 ,《Mixed-Ligand Metal-Organic Frameworks: Synthesis and Characterization of New MOFs Containing Pyridine-2,6-dimethanolate and Benzene-1,4-dicarboxylate Ligands》 appeared in European Journal of Inorganic Chemistry. The author of the article were Mylonas-Margaritis, Ioannis; Mayans, Julia; Efthymiou, Constantinos G.; McArdle, Patrick; Papatriantafyllopoulou, Constantina. The article conveys some information:

The development of synthetic approaches towards new mixed-ligand metal organic frameworks (MOFs) was attracting considerable attention recently as they display fascinating properties due to the synergistic effect between the different ligands. Herein, the initial combination of pyridine-2,6-dimethanol (H2pdm) with benzene-1,4-dicarboxylic acid (H2bdc) provided access to three new mixed-ligand MOFs, [M3(bdc)2(Hpdm)2]n (MII = ZnII, 1; MnII, 2) and [Mn3(bdc)3(H2pdm)2]n (3). 1-3 Are the first MOFs containing H2pdm in its neutral or anionic form. 1 And 2 are isostructural 2D MOFs with a square lattice (sql) framework topol., while 3 is a 3D MOF possessing a primitive cubic (pcu) topol. Dc magnetic susceptibility measurements for 3 demonstrate antiferromagnetic interactions between the MnII ions which is a combination of intra- and intertrimer exchange pathways.2,6-Pyridinedimethanol(cas: 1195-59-1Reference of 2,6-Pyridinedimethanol) was used in this study.

And the article was published in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2019. Electric Literature of C7H9NO2 The author mentioned the following in the article:

Covalent organic frameworks (COFs) have attracted considerable interest over the past few years, but the available type of monomers is still limited. Herein, two novel imine-linked COFs (TaDAP and TaDA) were constructed by the condensation of 1,3,5-tris-(4-aminophenyl) triazine with 2,6-diformylpyridine (forming TaDAP) and 1,3-benzenedialdehyde (forming TaDA) under solvothermal conditions. The structures of the COFs were confirmed and characterized by solid state 13C NMR, FT-IR, PXRD, TGA, SEM, TEM and nitrogen sorption isotherms. They appear as regular spherical particles and possess excellent thermal stability. It was also found that their dispersions emit strong fluorescence, and display quick response to certain metal ions. In particular, TaDAP can detect Fe3+ with sensitivity and selectivity. Moreover, both the COFs present excellent catalytic activity towards the Knoevenagel reaction. Accordingly, this study not only provides a new way to enrich the family of COFs, but also develops their potential applications in metal ion detection.
