Tetrapyrazinoporphyrazine substituted at its periphery with eight antioxidant 3,5-di-t-butyl-4-hydroxyphenyl groups behaves as a turn-on fluorescent sensor for fluoride anions. Conversely, the precursor antioxidant-substituted 1,2-phthalonitrile was found to act in turn-off mode suggesting that the origin of the phenomenon lies at the phenolate-substituted 1,4-pyrazinyl moiety.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile(SMILESS: N#CC1=NC(Cl)=C(Cl)N=C1C#N,cas:56413-95-7) is researched.Application of 400801-74-3. The article 《Crystalline salts of the ring-reduced tin(IV) dichloride hexadecachlorophthalocyanine and octachloro- and octacyanotetrapyrazinoporphyrazine macrocycles with strong electron-withdrawing ability》 in relation to this compound, is published in Dyes and Pigments. Let’s take a look at the latest research on this compound (cas:56413-95-7).

Substituted tin(IV) dichloride phthalocyanine and tetrapyrazinoporphyrazines with acceptor chloro- or cyano-substituents: SnIVCl2(PcCl16), SnIVCl2(TPyzPzCl8) and SnIVCl2{TPyzPz(CN)8}, where PcCl16 = hexadecachlorophthalocyanine; TPyzPz(CN)8 = octacyanotetrapyrazinoporphyrazine, TPyzPzCl8 = octachlorotetrapyrazinoporphyrazine were synthesized. The reduction of these metallomacrocycles by fullerene {cryptand(Na+)}(C•-60) salt (1, 3 and 4) or potassium graphite (KC8) in the presence of cryptand (2) yields crystalline anionic salts: {cryptand(Na+)}2[SnIVCl2(PcCl4-16)]2-·C6H4Cl2 (1), {cryptand(K+)}2[{SnII(PcCl4-16)}0.926{SnIVCl2(PcCl4-16)}0.074]2-·2C6H4Cl2 (2), {cryptand(Na+)}[SnIVCl2{TPyzPz(CN)•3-8}]•-·C6H4Cl2 (3) and {cryptand(Na+)}2[SnIVCl2(TPyzPzCl4-8)]2-·2C6H4Cl2 (4). Reduction of SnIVCl2(macrocycle2-) with dianion macrocycles is accompanied by the formation of radical trianion or tetraanion macrocycles in 1-4. As stronger reductant, KC8 reduces the macrocycle and in addition nearly complete metal centered reduction from tin(IV) to tin(II) took place. Strong blue shift of the Q-band and new absorption bands are observed in the NIR range in the spectra of 1-4. Partial disruption of macrocycle aromaticity and alternation of the C – Nmeso bonds were found for the reduced macrocycles. Macrocycles are planar, and SnIV atoms are positioned exactly in the macrocycle plane. The only exception is strong distortion of the PcCl16 macrocycle in SnII(PcCl4-16) (2). Structures of 1-4 contain layers from the macrocycles having the side-by-side contacts in 1, 2, 4 and separated by cationic layers. Salt 3 presents the first structure of the TPyzPz(CN)8 macrocycle with strongest acceptor properties among known porphyrins and porphyrazines. It was shown that tetraanion macrocycles are diamagnetic in 1, 2 and 4. The [SnIVCl2{TPyzPz(CN)8•3-}]•- radical anions are paramagnetic in 3 with effective magnetic moment of 1.64μB, and salt 3 shows moderate antiferromagnetic coupling of spins with Weiss temperature of -14 K.

Electric Literature of C6Cl2N4. 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: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Syntheses and Langmuir-Blodgett film formation of donor-acceptor molecules. Author is Zhu, Daoben; Yang, Chun; Liu, Yunqi; Xu, Yu.

Several novel organic mols. with donor-acceptor structure were designed and synthesized as non-linear optical (NLO) materials. Stable Langmuir films were formed at the air-water interface. Under appropriate exptl. conditions monolayers of these mols. were deposited in a Z-type mode. The Langmuir-Blodgett (LB) films were characterized by UV-visible spectroscopy, SEM and low-angle x-ray diffraction measurement. The NLO behavior of their monolayers was evaluated from second harmonic generation (SHG).

The article 《Cationic azaphthalocyanines bearing aliphatic tertiary amino substituents-Synthesis, singlet oxygen production and spectroscopic studies》 in relation to this compound, is published in Journal of Photochemistry and Photobiology, A: Chemistry. Let’s take a look at the latest research on this compound (cas:56413-95-7).

New cationic zinc azaphthalocyanines (AzaPc) were prepared using a statistical method of synthesis starting from 5,6-bis(2-diethylaminoethylsulfanyl)pyrazine-2,3-dicarbonitrile (A) and 5,6-bis(tert-butylsulfanyl)pyrazine-2,3-dicarbonitrile (B). All the six possible AzaPc derivatives were detected on TLC but only five of them were finally isolated using column chromatog. on silica (excluding AAAB type). The adjacent (AABB) and opposite (ABAB) isomers were well separated Singlet oxygen quantum yields (ΦΔ) were measured using the DPBF decomposition method. Values of ΦΔ in anhydrous DMF drastically decrease with the number of amino groups from 0.66 for BBBB type to 0.04 for AAAA type. The same dependence was observed in anhydrous DMF for the corresponding hydrochlorides. When DMF/water 95:5 added with HCl was used, the ΦΔ values for amino AzaPc increased to approx. 0.66. This suggests that solvation of the amino and Cl- ions plays an important role in the separation of the AzaPc mols. although no changes were found in UV-vis spectra. At least eight cationic charges are necessary for complete monomerization of AzaPc in water. Fewer charges lead to significant decrease of the absorption in the area of the Q-band and to pronounced dimeric character of the absorption spectrum.

COA of Formula: C6Cl2N4. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles.

Author is Husain, Ali; Ganesan, Asaithampi; Machacek, Miloslav; Cerveny, Lukas; Kubat, Pavel; Ghazal, Basma; Zimcik, Petr; Makhseed, Saad.

The development of new non-aggregated phthalocyanines bearing multivalent saccharide moieties on their macrocyclic rims is of great interest. Many characteristics, including water-solubility, non-toxicity and others, can be feasibly obtained by these amphiphiles which can be considered as a key solution for demonstrating highly efficient photoactive materials in water. Herein, a family of five newly prepared dually directional Zn(II) containing phthalocyanines (PcG1-4) and azaphthalocyanine (AzaPcG1) glycoconjugates is described. The unique spatial arrangement of the glucoside units based on peripherally hexadeca-(PcG1) and nonperipherally octa-(PcG4) macrocycles provides a fully monomeric behavior along with a high fluorescence (ΦF ~0.21) in aqueous solution These amphiphiles were characterized by low toxicity, and an extremely low cellular uptake was obtained due to the highly polar nature of the glucoside substituents. Accordingly, their potential as suitable photoactive chromophores for red-emitting extracellular fluorescent probes has been confirmed upon the evaluation of paracellular transport using a layer of MDCKII cells with the permeability coefficient fully comparable with an established evaluator of the integrity of the monolayer.

A new unsym. zinc azaphthalocyanine (AzaPc) was synthesized using statistical condensation of two precursors. Postsynthetic modifications led to incorporation of the azide group that efficiently underwent Cu(I)-catalyzed azide/alkyne 1,3-dipolar cycloaddition with terminal alkyne on a solid phase. The modified solid phase was then used for synthesis of oligodeoxyribonucleotides labeled with AzaPc. DNA hybridization assays confirmed high quenching efficiency (QE>96%) of zinc AzaPc quencher with six different fluorophores ranging in emission maxima from 517 nm to 701 nm (FAM, HEX, Cy3, Cy3.5, Cy5, and Cy5.5).

The article 《Synthesis and dyeing properties of dicyanopyrazine dyes》 in relation to this compound, is published in Journal of the Korean Fiber Society. Let’s take a look at the latest research on this compound (cas:56413-95-7).

Reaction of 2,3-dichloro-5,6-dicyanopyrazine with various Fischer’s base type enamines gave the corresponding 2-chloro-5,6-dicyanopyrazine derivatives The reactive-disperse dyes showed large differences in λmax from solution to solid state resulting from strong intermol. π-π interactions. These dyes have rather small mol. size but have a strong intramol. charge-transfer chromophoric system. The absorption maxima of these compounds were observed at 463∼560 nm. The electronic character of the substituents in the dyes strongly affects their absorption spectra, producing bathochromic shifts depending on both the basicity of the heterocyclic moiety and the enlargement of the π-conjugated system. The dyeability of 2 of the dyes toward polyester and nylon fiber were generally good. Wash, perspiration, and rubbing fastness were excellent, while light fastness was poor, probably due to the oxidation of the enamine moiety.

The herbicidal activities of 6-substituted 2,3-dicyano-5-chloropyrazines were evaluated and correlated with the previously reported substituent parameters π (hydrophobicity) and σp (Hansch, A., et al., 1973). Parameters π and π2 indicate that the hydrophobicity of the mol. is involved in the translocation of these compounds to the target site. The activity decreases with increasing electron-withdrawing property of the 6-substituent. The herbicidal activity varied parabolically with the change in π.
