Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about catena-Poly[[[4-amino-3,5-bis(pyridin-2-yl)-4H-1,2,4-triazole-κ2 N 1,N 5](dicyanamido-κN)copper(II)]-μ2-dicyanamido-κ2 N:N’]: coordination polymer chains linked into a bilayer by hydrogen bonds and π-π stacking interactions.Recommanded Product: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.

In the title compound, [Cu(C2N3)2(C12H10N6)]n or [Cu(dca)2(abpt)]n, where abpt is 4-amino-3,5-bis(pyridin-2-yl)-4H-1,2,4-triazole and dca is the dicyanamide anion, the CuII center is five-coordinate with an approx. square-pyramidal geometry. One of the two dicyanamide ligands is a terminal ligand, but the other one acts as a μ1,5-bridging ligand between pairs of CuII centers, so generating a one-dimensional coordination polymer. A combination of N-H···N and C-H···N hydrogen bonds, augmented by π-π stacking interactions, links the coordination polymer chains into a bilayer structure. Comparisons are made with some related CuII complexes containing dca ligands and heteroaromatic co-ligands.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Inhibitive properties, adsorption and a theoretical study of 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles as corrosion inhibitors for mild steel in perchloric acid, published in 2008-02-29, which mentions a compound: 1671-88-1, mainly applied to mild steel corrosion inhibitors triazoles adsorption perchloric acid, Recommanded Product: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.

Corrosion inhibition of mild steel in molar perchloric acid by 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles (n-PAT, n = 2, 3 and 4) was studied at 30 °C using gravimetric and electrochem. impedance spectroscopy techniques. Protection efficiencies of 95% and 92% were obtained with 12 × 10-4 M of 3-PAT and 4-PAT, resp.; while 2-PAT reached only 65%. The inhibiting properties of n-PAT were found to depend on the concentration and the order of increasing inhibition efficiency was correlated with the modification of the position of the nitrogen atom in the pyridinium substituent. It was shown that adsorption of 4-aminotriazole derivatives on the steel surface is consistent with the Langmuir adsorption isotherm and the obtained standard free energy of adsorption ( Δ G ads 0 ) values indicate that the corrosion inhibition of the mild steel in 1 M HClO4 is depends on both physic-and chemisorption. A significant correlation is obtained between inhibition efficiency and quantum chem. parameters using semi-empirical quant. structure-activity relationships (QSAR) approach.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about Bright photo- and triboluminescence of centrosymmetric Eu(III) and Tb(III) complexes with phosphine oxides containing azaheterocycles.Electric Literature of C17H14NP.

Six centrosym. mononuclear Eu3+ and Tb3+ complexes of the type [LnL2(hfac)3] were synthesized employing diphenyl(pyridin-2-yl)phosphine oxide (Ph2P(O)Py), diphenyl(pyridimin-2-yl)phosphine oxide (Ph2P(O)Pym), and diphenyl(pyrazin-2-yl)phosphine oxide (Ph2P(O)Pyr) as supporting ligands (L). The complexes [LnL2(hfac)3] (L = Ph2P(O)Py and Ph2P(O)Pyr) comprise an eight-coordinate Ln3+ ion with two monodentate O-donor phosphine oxides and three bidentate hfac- anions. In the [Ln{Ph2P(O)Pym}2(hfac)3] complexes, the Ln3+ ion is nine-coordinated by three bidentate hfac- anions and two Ph2P(O)Pym ligands, one of which is bound to Ln in a N,O-bidentate chelating mode, and the other acts as a monodentate O-donor ligand. The complexes display bright solid-state photoluminescence with emission quantum yields up to 56%. The integral intensity of 5D0 → 7F2 transition in the emission spectra of the Eu(III) complexes strongly depends on the coordination environment of the Eu3+ ion. The asym. coordination geometry around Eu3+ results in the large radiative rate constants The crystals of the Eu(III) and Tb(III) complexes exhibit triboluminescence upon breaking under ambient conditions. The relation between the triboluminescent properties and crystal structures of the complexes is discussed.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds.

Related Products of 1671-88-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about Influence of aminotriazole additives in electrolytic solution on dye-sensitized solar cell performance. Author is Kusama, Hitoshi; Arakawa, Hironori.

The influence of aminotriazole additives in acetonitrile solution of an I-/I3- redox electrolyte on the performance of a bis(tetrabutylammonium)cis-bis(thiocyanato)bis(2,2′-bipyridine-4-carboxylic acid, 4′-carboxylate)ruthenium(II) (N719) dye-sensitized TiO2 solar cell was studied. The current-voltage characteristics were investigated under AM 1.5 (100 mW/cm2) for 10 different aminotriazole compounds The aminotriazole additives tested had varying effects on the solar cell performance. Most of the additives enhanced the open-circuit photovoltage (Voc), fill factor (ff) and the solar energy conversion efficiency (η), but reduced the short circuit photocurrent d. (Jsc) of the solar cell. The highest η of 7.6% was obtained by adding 3-amino-1H-1,2,4-triazole and η was comparable to that of 4-t-butylpyridine (TBP). Both the phys. and chem. properties of the aminotriazoles were computationally calculated in order to determine the reasons why the additive affects the solar cell performance. The greater the calculated partial charge of the nitrogen atoms in the mol., the larger the Voc value. The Voc of the solar cell also increased as the size of the aminotriazole mols. decreased. The Jsc value increased with increasing the absolute difference in the dipole moments between the calculated aminotriazoles and acetonitrile. These results suggest that the electron donicity of the aminotriazole additives influenced the interaction with the TiO2 photoelectrode and the solvent, which altered the dye-sensitized solar cell performance.

Compounds were prepared in excellent isolated yields (90-98%) within 4 min in a closed vessel by treating indoles with disulfides in the presence of sodium hydride in anhydrous N,N-dimethylformamide. The method was not affected by electron-donating and -withdrawing substituents both on 3-arylthio moiety and at 2- and 5-positions of the indole nucleus.
