Synthetic Route of C5H7N3In 2021 ,《Tris(oxalato)chromate(III) hybrid salts templated by pyridinium and mixed pyridinium-ammonium cations: synthesis, structures and magnetism》 was published in Journal of Coordination Chemistry. The article was written by Choubeu, Coustel M. N.; Ndosiri, Bridget N.; Vezin, Herve; Minaud, Claire; Orton, James B.; Coles, Simon J.; Nenwa, Justin. The article contains the following contents:

By modifying the stoichiometric ratio of starting materials, two tris(oxalato)chromate(III) salts, (C7H11N2)3[Cr(C2O4)3] and (C5H8N3)2(NH4)[Cr(C2O4)3]·2H2O {(C7H11N2)+ = 2-amino-4,6-dimethylpyridinium, (C5H8N3)+ = 2,6-diaminopyridinium}, were synthesized and characterized by elemental and thermal analyses, single-crystal x-ray diffraction, IR and UV – visible spectroscopies, EPR and SQUID measurements. Salt exhibits a 3-D supramol. framework based on [Cr(C2O4)3]3- and 2-amino-4,6-dimethylpyridinim cations, (C7H11N2)+, via N-H···O hydrogen bonds. π-π Stacking interactions between pyridine rings contribute to the stabilization of the crystal packing. In contrast to salt, no π-π stacking interactions are observed in the mixed-cation salt and its crystal packing is consolidated by N-H···O and O – H···O hydrogen bonds. EPR spectra of and are consistent with the oxidation state +3 of the chromium center in an octahedral environment. Temperature-dependence of the magnetic susceptibility data studied from 2 to 300 K revealed the existence of zero-field splitting effects (ZFS) for Cr(III) ions in both compounds In the experiment, the researchers used 2,6-Diaminopyridine(cas: 141-86-6Synthetic Route of C5H7N3)

And the article was published in Environmental Science and Pollution Research in 2019. Recommanded Product: 2,6-Diaminopyridine The author mentioned the following in the article:

The efficient removal of heavy metals from aqueous environment is imperative and challenging. A novel ternary composite constructed of diaminopyridine polymers, graphene oxide, and ferrite magnetic nanoparticles was designed by a facile in situ polymerization strategy for the removal of Pb(II) from aqueous solution Detailed characterization of morphol., chem., and magnetic properties was employed systematically to confirm the formation of the composite material. Batch adsorption experiment studies suggested that the composite was an excellent adsorbent for Pb(II) which was easily collected after use via exposure to an external magnetic field for 30 s. The effects of different parameters such as solution pH, adsorbent dosage, contact time, initial Pb(II) concentration, temperature, and co-existing ions were examined The maximum adsorption capacity at pH = 5 was estimated to be 387.2 mg g-1 at 298 K by the Langmuir isotherm model, accompanied by favorable adsorption recyclability according to the investigation of regeneration experiments Thermodn. studies revealed that the Pb(II) adsorption via our ternary composite was endothermic and spontaneous. The corresponding removal performance for effluent containing Pb(II) from the battery industry was successfully examined The present results indicated that our designed adsorbent is beneficial to the practical Pb(II) removal in wastewater purification In the experimental materials used by the author, we found 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 2,6-Diaminopyridine)

In 2019,Journal of the American Chemical Society included an article by Santos, Peter J.; Cao, Zhen; Zhang, Jianyuan; Alexander-Katz, Alfredo; Macfarlane, Robert J.. Recommanded Product: 2,6-Diaminopyridine. The article was titled 《Dictating Nanoparticle Assembly via Systems-Level Control of Molecular Multivalency》. The information in the text is summarized as follows:

Nanoparticle assembly can be controlled by multivalent binding interactions between surface ligands, indicating that more precise control over these interactions is important to design complex nanoscale architectures. It has been well-established in natural materials that the arrangement of different mol. species in three dimensions can affect the ability of individual supramol. units to coordinate their binding, thereby regulating the strength and specificity of their collective mol. interactions. However, in artificial systems, limited examples exist that quant. demonstrate how changes in nanoscale geometry can be used to rationally modulate the thermodn. of individual mol. binding interactions. As a result, the use of nanoscale design features to regulate mol. bonding remains an underutilized design handle to control nanomaterials synthesis. Here we demonstrate a polymer-coated nanoparticle material where supramol. bonding and nanoscale structure are used in conjunction to dictate the thermodn. of their multivalent interactions, resulting in emergent bundling of supramol. binding groups that would not be expected on the basis of the mol. structures alone. Addnl., we show that these emergent phenomena can controllably alter the superlattice symmetry by using the mesoscale particle arrangement to alter the thermodn. of the supramol. bonding behavior. The ability to rationally program mol. multivalency via a systems-level approach therefore provides a major step forward in the assembly of complex artificial structures, with implications for future designs of both nanoparticle- and supramol.-based materials. In the part of experimental materials, we found many familiar compounds, such as 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 2,6-Diaminopyridine)

The article was written by Santos, Peter J.; MacFarlane, Robert J.. The article contains the following contents:

Assembling superparamagnetic particles into ordered lattices is an attractive means of generating new magnetically responsive materials, and is commonly achieved by tailoring interparticle interactions as a function of the ligand coating. However, the inherent linkage between the collective magnetic behavior of particle arrays and the assembly processes used to generate them complicates efforts to understand and control material synthesis. Here, the authors use a synergistic combination of a chem. force (hydrogen bonding) and magnetic dipole coupling to assemble polymer-brush coated superparamagnetic Fe oxide nanoparticles, where the relative strengths of these interactions can be tuned to reinforce one another and stabilize the resulting superlattice phases. The authors can precisely control both the dipole-dipole coupling between nanoparticles and the strength of the ligand-ligand interactions by modifying the interparticle spacing through changes to the polymer spacer between the hydrogen bonding groups and the nanoparticles’ surface. This results in modulation of the materials’ blocking temperature, as well as the stabilization of a unique superlattice phase that only exists when magnetic coupling between particles is present. Using magnetic interactions to affect nanoparticle assembly in conjunction with ligand-mediated interparticle interactions expands the potential for synthesizing predictable and controllable nanoparticle-based magnetic composites.

《Investigating the effects of thickness on the performance of ZnO-based DSSC》 was written by Kouhestanian, E.; Ranjbar, M.; Mozaffari, S. A.; Salaramoli, H.. Category: pyridine-derivativesThis research focused onzinc oxide dye sensitized solar cell investigating effect. The article conveys some information:

Zinc oxide nanostructures exhibit unique properties which make them suitable for dye-sensitized solar cell applications. Their specific properties such as appropriate optical properties, proper energy band gap and high electron transfer characteristics have motivated researchers to use them in the fabrication of dye-sensitized solar cell photo-anodes. In the present study, the effect of thickness on the performance of a new ZnO photo-anode has been studied. All the photovoltaic parameters of the cells fabricated using N719 ruthenium dye were measured. SEM technique was utilized to determine the thickness and the UV-Visible method was used to study the transparent properties of the photo-anodes. Electrochem. impedance spectroscopy technique was employed to determine the appropriate equivalent circuit for studying the electron transfer mechanisms in all the fabricated cells. The results demonstrated that the ZnO thickness is a critical parameter for providing either sufficient resistance to suppress the charge recombination process or appropriate electron transferring properties. The optimized ZnO photo-anode was obtained at a thickness of 19μm, which resulted in an efficiency of 3.22%.

The syntheses and phase transition behaviors of liquid crystals composed of triangular π;-conjugated mols., 1,3,4,6,9b-pentaazaphenalene (5AP) was discussed. Three types of 5AP derivatives having 3,4,5-tris(dodecyloxy)phenyl ((OC12)3Ph) were prepared by changing substituent positions. From thermal and structural analyses, liquid crystalline phases were observed from all derivatives According to structural data and phase transition behaviors, it was suggested that the positions of the substituents significantly influence mol. alignments in liquid crystals as well as thermal properties. In particular, the columnar structures, which were favorable for expressing efficient carrier transportation, were observed in the 5AP derivative These results suggested that the 5AP scaffold could be a platform for constructing a variety of aggregated structures by slightly different patterns of the mol. structures. Plausible models for these transitions were discussed. The experimental process involved the reaction of 2,6-Diaminopyridine(cas: 141-86-6Synthetic Route of C5H7N3)

《The synthesis of a hexameric expanded hemiporphyrazine》 was written by Schrage, Briana R.; Chanawanno, Kullapa; Crandall, Laura A.; Ziegler, Christopher J.. Computed Properties of C5H7N3 And the article was included in Journal of Porphyrins and Phthalocyanines in 2020. The article conveys some information:

In this report the synthesis and characterization of a new hexameric expanded hemiporphyrazine which refer to as hexahemiporphyrazine were presented. The synthesis incorporated bis(6-amino-2-pyridyl)amine as a starting material, which could be produced from 2,6-diaminopyridine using melt reaction conditions. Bis(6-amino-2-pyridyl)amine can adopt three different conformations, two of which are observed in the free base and protonated form, and the third in the backbone of hexahemiporphyrazine. Reaction of bis(6-amino-2-pyridyl)amine and diiminoisoindoline in the presence of a catalytic amount of BF3 produces the hexihemiporphyrazine macrocycle, which was characterized spectroscopically and by X-ray crystallog. Structure elucidation reveals two inverted pyridine rings in a configuration reminiscent of that seen in hexaphyrin, however hexahemiporphyrazine lacks cross conjugation across the macrocycle.

And the article was published in International Journal of Biological Macromolecules in 2019. Formula: C5H7N3 The author mentioned the following in the article:

In the present study, 2, 6-diaminopyridine (PD) and polyamine compounds (ethylenediamine (EDA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA)) were used to modify chitosan (CS). The obtained derivatives (PD-CS, PD-EDA-CS, PD-TETA-CS, and PD-TEPA-CS) were identified and employed as adsorbents in batch experiments for the removal of Hg(II) from aqueous solutions The results confirmed that successful modification improves the Hg(II) adsorption significantly compared to pristine CS. The adsorbed amounts of Hg(II) increased gradually and reached maxima at pH values above 4.0 for all derivatives The Hg(II) adsorption equilibrium state was achieved within 12 h, with the process driven by a pseudo-second-order kinetic model. The Langmuir model effectively interpreted the Hg(II) adsorption isotherms; the maximum adsorption capacities for Hg(II) ions at 295 K were 172.7, 303.6, 276.0, and 230.6 mg/g for PD-CS, PD-EDA-CS, PD-TETA-CS, and PD-TEPA-CS, resp. High temperature and low ionic strength favored Hg(II) adsorption. The Hg(II)-loaded CS derivative was easily regenerated and showed acceptable reusability. The further FT-IR and XPS analyses indicate that the Hg(II) adsorption is governed by a process combining electrostatic attraction and a coordination reaction. The CS derivatives produced from polyamine-co-2, 6-diaminopyridine covalently bonded onto CS are promising adsorbents for the adsorptive removal of Hg(II) from an aqueous solution In the part of experimental materials, we found many familiar compounds, such as 2,6-Diaminopyridine(cas: 141-86-6Formula: C5H7N3)
