The author of the article were Mousa, Emad S.; Mahmoud, Walaa H.. The article conveys some information:

A novel Schiff base ligand (L) was prepared through condensation of 2,6-diaminopyridine and dibenzoyl methane in a 1:1 ratio. This Schiff base ligand was used for complex formation reaction with Fe(III) chloride. The structures of the ligand and its complex were deduced from elemental analyses, mass spectroscopy, 1H NMR, IR, UV-visible, electronic spectra, magnetic moment, molar conductivity measurements, thermogravimetric analyses and x-ray diffraction. The mol. and electronic structures of both ligand and complex were optimized theor. using d. function theory (DFT) method. Moreover, the antimicrobial activities of the prepared compounds were studied and proven against some pathogenic bacteria. The Fe(III) complex had higher biol. activity than that of the free ligand. Proceeding from the collected information, the properties of the complex were further studied. The particle size was determined by dynamic light scattering technique to be 92.59 nm. Textural properties of the nano complex were studied by N2 adsorption to estimate the sp. surface area, pore volume and pore size distribution. The pores in the complex were found in the micropore-mesopore range. Differential scanning calorimetric measurements reveal the existence of four endothermic peaks at 243.8, 308, 339.8 and 380.5 K. Dielec. properties and conductivity were scanned at different frequencies and temperatures The dielec. constant reaches a peak value of 600 at ∼390 K, 30 Hz. A cross-over from the universal dielec. response to the super linear power law of conductivity is reported for this complex at T ≤ 345 K. Finally, the AC-magnetic susceptibility measurements were carried out in the low-temperature region. The complex showed paramagnetic behavior with a slight change in the magnitude of its magnetic moment at T = 244 K. In the experimental materials used by the author, we found 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 141-86-6)

The current preliminary investigation presents for the first time the synthesis of grafted copolymer Poly (DAP-g-Th) from 2,6-diaminopyridine (DAP) and thiophene (Th) via chem. oxidative copolymerization using ferric chloride as an oxidizing agent for enhancing its photoluminescence properties. Modifications via copolymerization were confirmed by optical, morphol., and spectral anal. through FT-IR, UV-Visible, XRD, fluorescence studies. Increased value of oscillator strength, molar extinction coefficient, and lowered bandgap were observed in the case of poly(DAP-g-Th). FT-IR results showing alteration in the properties of polymer lying intermediate between individual monomers confirming copolymerization Intermediate quantum yield value disclosing transformations in the electronic structure of the poly(DAP-g-Th). Morphol. studies also suggested the intermediate property of copolymer. Poly(DAP-g-Th) showed the best antioxidant activity against DPPH free radical assay and its IC50 value was reported 0.024 ± 0.001 mg/mL.

Quality Control of 2,6-DiaminopyridineIn 2021 ,《Toward Robust, Tough, Self-Healable Supramolecular Elastomers for Potential Application in Flexible Substrates》 was published in ACS Applied Materials & Interfaces. The article was written by Fan, Jianfeng; Huang, Jiarong; Gong, Zhou; Cao, Liming; Chen, Yukun. The article contains the following contents:

A robust, tough, and self-healable elastomer is a promising candidate for substrate in flexible electronic devices, but there is often a trade-off between mech. properties (robustness and toughness) and self-healing. Here, a poly(dimethylsiloxane) (PDMS) supramol. elastomer is developed based on metal-coordinated bonds with relatively high activation energy. The strong metal-coordination complexes and their corresponding ionic clusters acting as the crosslinking points strengthen the resultant supramol. networks, which achieves superior mech. robustness (2.81 MPa), and their consecutive dynamic rupture and reconstruction efficiently dissipate strain energy during the stretching process, which leads to an impressive fracture toughness (32 MJ/m3). Addnl., the reversible intermol. interactions (weak hydrogen bonds and strong sacrificial coordination complexes/clusters) can break and re-form upon heating; thus, the elastomer self-heals at a moderate temperature with the highest healing efficiency of 95%. As such, the potential of the as-prepared supramol. elastomer for a substrate material of flexible electronic devices is discovered. The experimental part of the paper was very detailed, including the reaction process of 2,6-Diaminopyridine(cas: 141-86-6Quality Control of 2,6-Diaminopyridine)
