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. Compound: 56413-95-7, is researched, Molecular C6Cl2N4, about Synthesis and studies on photodynamic activity of new water-soluble azaphthalocyanines, the main research direction is photodynamic activity water soluble azaphthalocyanine derivative; photosensitized photooxidation phenylisobenzofurane azaphthalocyanine derivative singlet oxygen generation.Category: chiral-oxygen-ligands.

Aza analogs of phthalocyanines (AzaPc’s) bearing four long chains with carboxy groups at the end and four “”bulky”” diethylamino groups on periphery were synthesized and characterized. Their sodium salts are very soluble in water. The first studies on photodynamic activity of this tetrapyrazinoporphyrazines (a type of AzaPc) are presented. The dye-sensitized photooxidation of 1,3-diphenylisobenzofurane via 1O2 was studied in pyridine. Their photodynamic activity in vitro was not detected due to the aggregation behavior of these compounds in water.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 56413-95-7, is researched, SMILESS is N#CC1=NC(Cl)=C(Cl)N=C1C#N, Molecular C6Cl2N4Journal, Dyes and Pigments called Bulky 2,6-diphenylphenylsulfanyl substituents efficiently inhibit aggregation in phthalocyanines and tetrapyrazinoporphyrazines and control their photophysical and electrochemical properties, Author is Zimcik, Petr; Malkova, Anna; Hruba, Lenka; Miletin, Miroslav; Novakova, Veronika, the main research direction is magnesium zinc sulfanyl phthalocyanine tetrapyrazinoporphyrazine complex preparation redox potential; fluorescence magnesium zinc sulfanyl phthalocyanine tetrapyrazinoporphyrazine complex.Synthetic Route of C6Cl2N4.

Octasubstituted zinc, metal-free and magnesium complexes of phthalocyanine and tetrapyrazinoporphyrazine bearing very bulky 2,6-diphenylphenylsulfanyl substituents were synthesized. The substituents efficiently inhibited aggregation of the dyes and only monomers were detected even at a concentration of 200 μM solution in toluene. Photophys. data indicated influence of the heavy-atom effect – magnesium complexes were more fluorescent (ΦF 0.40-0.51) and zinc complexes produced stronger the singlet oxygen (ΦΔ 0.56-0.72) in both series of compounds The presence of addnl. nitrogens in tetrapyrazinoporphyrazine core made it substantially more electron deficient when compared with corresponding phthalocyanine analogs. 2,6-Diphenylphenylsulfanyl substituents also increased electron deficient character of the core and influenced the photophys. properties.

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 Preparation of magnesium azaphthalocyanines by cyclotetramerization of S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles, published in 1996-12-31, which mentions a compound: 56413-95-7, mainly applied to magnesium azaphthalocyanine preparation cyclization disulfanylpyrazine dicarbonitrile; sulfanylpyrazine dicarbonitrile cyclization magnesium azaphthalocyanine preparation; carbonitrile disulfanylpyrazine cyclization magnesium azaphthalocyanine preparation; substituent cyclization disulfanylpyrazine dicarbonitrile azaphthalocyanine preparation, COA of Formula: C6Cl2N4.

Four novel S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles were obtained in a multistep synthesis from diaminomaleonitrile. Two of these dicarbonitriles, with Et or benzyl S-substituents, give pure Mg azaphthalocyanines in good yields when reacted with Mg propoxide in PrOH and dioxane. Aromatic S-substituents are less stable during the reaction conditions used for cyclizations, and product mixtures were obtained.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Effective Monofunctional Azaphthalocyanine Photosensitizers for Photodynamic Therapy, published in 2009, which mentions a compound: 56413-95-7, Name is 5,6-Dichloropyrazine-2,3-dicarbonitrile, Molecular C6Cl2N4, HPLC of Formula: 56413-95-7.

In this work we present a rational design of the active part of third generation photosensitizers for photodynamic therapy based on phthalocyanine and an azaphthalocyanine core. The preferred zinc complexes of the AAAB type that contain bulky tert-butylsulfanyl substituents (A) and one carboxy group (B) have been synthesized by statistical condensation and fully characterized. The tetramerization was performed using magnesium(ii) butoxide followed by demetalation and insertion of ZnII. Compound 1 synthesized from 4,5-bis(tert-butylsulfanyl)phthalonitrile (A) and 2,3-dicyanoquinoxaline-6-carboxylic acid (B) exerted very promising photophys. properties (Q-band absorption at 726 nm, ε = 140000 M-1 cm-1), which allowed strong absorption of light at long wavelengths where the penetration of the light through human tissues is deeper. The very high singlet oxygen quantum yield of 1 (ΦΔ = 0.80) assures efficient photosensitization. As a result of bulky peripheral substituents, compound 1 shows good solubility in organic solvents with a low degree of aggregation, which makes it potentially viable for noncomplicated modification. One carboxy group in the final structure of 1 allows simple binding to possible carriers. This compound is suitable for binding to targeting moieties to form the highly active part of a third-generation photosensitizer.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Structural factors influencing the intramolecular charge transfer and photoinduced electron transfer in tetrapyrazinoporphyrazines, published in 2014, which mentions a compound: 56413-95-7, Name is 5,6-Dichloropyrazine-2,3-dicarbonitrile, Molecular C6Cl2N4, Application of 56413-95-7.

Unsym. tetrapyrazinoporphyrazines (TPyzPzs) from the group of azaphthalocyanines with one peripherally attached amino substituent (donor) were synthesized, and their photophys. properties (fluorescence quantum yield and singlet oxygen quantum yield) were determined The synthesized TPyzPzs were expected to undergo intramol. charge transfer (ICT) as the main pathway for deactivating their excited states. Several structural factors play a critical role in ICT efficiency. The substituent in the ortho position to the donor center significantly influences the ICT, with tert-butylsulfanyl and butoxy substituents inducing the strongest ICTs, whereas chloro, Me, Ph, and hydrogen substituents in this position reduce the efficiency. The strength of the donor pos. influences the ICT efficiency and correlates well with the oxidation potential of the amines used as the substituents on the TPyzPz as follows: n-butylamine < N,N-diethylamine < aniline < phenothiazine. The ICT (with conjugated donors and acceptors) in the TPyzPz also proved to be much stronger than a photoinduced electron transfer in which the donor and the acceptor are connected through an aliphatic linker.

Thirteen new, stable, push-pull systems featuring dimethylamino and pyrazine-2,3-dicarbonitrile moieties as the donor and acceptor, resp., and systematically extended and varied π-linkers were prepared and studied. Evaluation of the measured UV/Vis spectra, electrochem. data (cyclic voltammetry, rotating disk voltammetry, and polarog.), x-ray data, and exptl. determined and calculated hyperpolarizability values enabled structure-property studies; these revealed some important structural features that affected the efficiency of intramol. charge-transfer and nonlinear optical properties in this class of heterocyclic push-pull chromophores. The charge-transfer transition was most significantly affected by structural features such as π-linker length, chromophore planarity, and the number of 1,4-phenylene/ethynylene subunits in the π-linker.
