《Functionalization of partially reduced graphene oxide by metal complex as electrode material in supercapacitor》 was written by Bakhshandeh, Mohammad Bagher; Kowsari, Elaheh. COA of Formula: C5H7N3 And the article was included in Research on Chemical Intermediates in 2020. The article conveys some information:

High elec. conductivity and high surface area are two main parameters which affect supercapacitor electrode performance. Graphene has gained prominence in electrode of elec. double-layer capacitor due to its high elec. conductivity and high sp. surface area. Functionalization of partially reduced graphene oxide is the state-of-the-art method in synthesis of graphene system which is used in electrode of elec. double-layer capacitors (EDLCs). In this study, graphene system was functionalized by 2,6-diaminopyridine cobalt complex with a simple method in available and engineered porous surface area to eliminate agglomeration of graphene sheets and enhance elec. conductivity of them which is suitable for EDLCs. Curved and porous structure that obtained high and available surface area for supercapacitor electrodes was approved by structural anal. such as X-ray diffraction, Raman spectroscopy, SEM and Brunauer-Emmett-Teller. Furthermore, the XPS and Fourier-transform IR were used for elemental anal. Also, galvanostatic charge/discharge (GCD), cyclic voltammetry and electrochem. impedance spectroscopy were applied to specify electrochem. behavior of the prepared electrode. Accordingly, the elec. resistance obtained was 5.23 Ω. The specific capacitance obtained was 192 F/g by cyclic voltammetry and 107 F/g by GCD methods.2,6-Diaminopyridine(cas: 141-86-6COA of Formula: C5H7N3) was used in this study.

《A highly sensitive “”ON-OFF”” optical sensor for the selective detection of cyanide ions in 100% aqueous solutions based on hydrogen bonding and water assisted aggregation induced emission》 was written by Nazarian, Ramo; Darabi, Hossein Reza; Aghapoor, Kioumars; Firouzi, Rohoullah; Sayahi, Hani. Reference of 2,6-Diaminopyridine And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:

Nanoparticles N,N’-(pyridine-2,6-diyl)bis(2-(2,4-dichlorophenoxy)acetamide) exhibited an “”on-off”” emission response toward cyanide (CN-) ions in 100% aqueous solutions based on AIE features. AIEgen 1 is an easy-to-use probe that exhibits rapid response (5 s), extremely high sensitivity (limit of detection = 8.2 nM) and excellent selectivity. The sensing performance of CN- through a test kit and bitter seed solutions was good. The exptl. results show that compound 1 is planar and can self-assemble into a supramol. system and show blue emission. Then, CN- destroys both hydrogen bonds and the aggregates of 1 and quenches the emission. This process is reversible upon the addition of HCl solution In addition to this study using 2,6-Diaminopyridine, there are many other studies that have used 2,6-Diaminopyridine(cas: 141-86-6Reference of 2,6-Diaminopyridine) was used in this study.

And the article was published in Journal of Porphyrins and Phthalocyanines in 2019. Recommanded Product: 141-86-6 The author mentioned the following in the article:

It was established that microwave irradiation solvent-free processing of 2,6-diaminopyridine or 1,3-phenylenediamine with phthalonitrile or 4-tert-butylphthalonitrile led to corresponding hemiporphyrazines I (X = N, CH; Y = H, t-Bu; X = CH, Y = t-Bu, Z = H; X = CH, Y = H, Z = t-Bu) with sufficiently high yields and a huge reduction in the time required for synthesis, from 8-12 h to 20 min. The Knudsen effusion method with mass spectrometric control of vapor composition was applied. The mass spectrometric investigations established that the macrocyclic compounds I give a stable stream of particles and their enthalpies of sublimation were estimated by the second law of thermodn.

Yang, Weixiang; Tang, Shuihua; Huang, Qiankuan; Zhang, Qian; Tang, Zhen; Yang, Shuang published their research in Journal of Materials Science: Materials in Electronics in 2021. The article was titled 《Highly effective Fe-N-C electrocatalysts toward oxygen reduction reaction originated from 2,6-diaminopyridine》.Quality Control of 2,6-Diaminopyridine The article contains the following contents:

Fe-N-C electrocatalysts have been intensively studied due to their extraordinary catalytic activity toward oxygen reduction reaction (ORR). Here we prepare a Fe-N-C electrocatalyst through cost-effective and nontoxic precursors of 2,6-diaminopyridine (DAP) and FeCl3, where iron ions react with DAP to formed Fe-Nx species first, followed by polymerization and pyrolysis. X-ray diffraction patterns display no obvious Fe2O3 peaks observed in the catalyst as the nominal content of iron addition is less than 10 wt%. XPS spectra indicate that the catalyst has rich pyridinic nitrogen, graphitic nitrogen and Fe-Nx species, which are considered as active sites for ORR. Therefore the catalyst demonstrates an excellent catalytic activity with an onset potential of about 0.96 V, half-wave potential of about 0.84 V, and a limiting c.d. of 5.8 mA cm-2, better than com. Pt/C catalyst in an alk. medium. Furthermore its stability is also much more excellent than that of Pt/C. This work provides a strategy to synthesize universal M-N-C catalysts.2,6-Diaminopyridine(cas: 141-86-6Quality Control of 2,6-Diaminopyridine) was used in this study.

In triplex-forming peptide nucleic acid, a novel 2-guanidyl pyridine nucleobase (V) enables recognition of up to two cytosine interruptions in polypurine tracts of dsRNA by engaging the entire Hoogsteen face of C-G base pair. Ab initio and mol. dynamics simulations provided insights into H-bonding interactions that stabilized V·C-G triplets.

Safety of 2,6-DiaminopyridineIn 2019 ,《Secondary Electrostatic Interaction Model Revised: Prediction Comes Mainly from Measuring Charge Accumulation in Hydrogen-Bonded Monomers》 was published in Journal of the American Chemical Society. The article was written by van der Lubbe, Stephanie C. C.; Zaccaria, Francesco; Sun, Xiaobo; Guerra, Celia Fonseca. The article contains the following contents:

The secondary electrostatic interaction (SEI) model is often used to predict and explain relative hydrogen bond strengths of self-assembled systems. The SEI model oversimplifies the hydrogen-bonding mechanisms by viewing them as interacting point charges, but nevertheless exptl. binding strengths are often in line with the model’s predictions. To understand how this rudimentary model can be predictive, we computationally studied two tautomeric quadruple hydrogen-bonded systems, DDAA-AADD and DADA-ADAD. Our results reveal that when the proton donors D (which are electron-donating) and the proton acceptors A (which are electron-withdrawing) are grouped together as in DDAA, there is a larger accumulation of charge around the frontier atoms than when the proton donor and acceptor groups are alternating as in DADA. This accumulation of charge makes the proton donors more pos. and the proton acceptors more neg., which enhances both the electrostatic and covalent interactions in the DDAA dimer. The SEI model is thus predictive because it provides a measure for the charge accumulation in hydrogen-bonded monomers. Our findings can be understood from simple phys. organic chem. principles and provide supramol. chemists with meaningful understanding for tuning hydrogen bond strengths and thus for controlling the properties of self-assembled systems.

《Optical detection of cyanide by palladium(II)-dithiazolopyridine probe at the parts per billion level》 was written by Ebadinia, Leila; Darabi, Hossein Reza; Ramazani, Ali. Quality Control of 2,6-Diaminopyridine And the article was included in Phosphorus, Sulfur and Silicon and the Related Elements in 2020. The article conveys some information:

The ensemble of 2,6-bis(2-chlorophenyl)dithiazolo[4,5-b:5′,4′-e]pyridine with Pd2+ ions (•Pd2+) was prepared for the detection of cyanide ions (CN-) in 50% aqueous methanol. Among the tested metal ions, only Pd2+ sensitively induced the red shift of the absorption bands and the complete decrease of fluorescence emission. The detection limit toward Pd2+ was 2 ppb. The ensemble •Pd2+ selectively and rapidly detected a low concentration of cyanide ions by a colorimetric change (40 ppb) as well as a “”turn-on”” fluorescent response (5 ppb). Job’s plot revealed the complex formation with 1:1 stoichiometry. The binding and replacement mode of •Pd2+ and CN- were also confirmed by 1H NMR titrations and IR anal. In general, a fast and selective recognition of CN- is reported. In the experiment, the researchers used 2,6-Diaminopyridine(cas: 141-86-6Quality Control of 2,6-Diaminopyridine)

In 2022,Bhalla, Parul; Tomer, Nisha; Bhagat, Pooja; Malhotra, Rajesh published an article in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy. The title of the article was 《Chromone functionalized pyridine chemosensor for cupric ions detection》.Product Details of 141-86-6 The author mentioned the following in the article:

A new Schiff base 2-ethoxy-3-{[(6-{[(2-ethoxy-4-hydroxy-2H-chromen-3-yl)methylidene]amino}pyridine-2-yl)imino]methyl}-2H-chromen-4-ol (CD) was synthesized as a result of the condensation of 2,6-diaminopyridine and 3-formyl chromone in 1:2 M ratio and used for cupric ions detection and characterized through FTIR, HRMS and 1H NMR spectral techniques. The sensing capability of Schiff base for cupric ions as compared to other transition metal ions was examined by absorbance and emission studies. A considerable decrease in emission intensity appeared in Schiff base in the case of cupric ions while irrelevant changes were examined for the rest of the ions. The binding stoichiometry was obtained as 1:2 for CD: Cu2+ complex intended from the job′s plot which was confirmed through HRMS spectral technique. DFT calculations were carried for the confirmation of structural relationships and absorption-emission data. The Regression coefficient, Limit of detection, and Association constant were obtained as 98.7%, 1.2 x 10-6 M, and 3.26 x 104 M-1 resp. using Benesi-Hildebrand (B-H) equation. The sensing power of Schiff base CD to recognize cupric ions was unaltered by the addition of the rest of metal ions, which was authenticated through interference studies. Schiff base CD and its complex with cupric ions were found stable over an extensive time period as revealed by time-reliant studies. The data collected by pH studies revealed that the preferred pH range for detecting cupric ions by Schiff base CD was 6 to 11. The Schiff base was finally utilized for sensing cupric ions in a variety of spiked samples of water like canal water, tap water, groundwater, distilled water.
