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 Bulky 2,6-diphenylphenylsulfanyl substituents efficiently inhibit aggregation in phthalocyanines and tetrapyrazinoporphyrazines and control their photophysical and electrochemical properties, published in 2017-01-31, which mentions a compound: 56413-95-7, mainly applied to magnesium zinc sulfanyl phthalocyanine tetrapyrazinoporphyrazine complex preparation redox potential; fluorescence magnesium zinc sulfanyl phthalocyanine tetrapyrazinoporphyrazine complex, COA of Formula: 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.
Here is just a brief introduction to this compound(56413-95-7)COA of Formula: C6Cl2N4, more information about the compound(5,6-Dichloropyrazine-2,3-dicarbonitrile) is in the article, you can click the link below.
