Synthesis of A3B zinc tetrapyrazinoporphyrazine covalently functionalized reduced graphene oxide
In this Letter, a novel strategy was applied to the preparation of tetrapyrazinoporphyrazine-reduced graphene oxide hybrid material. Reduced graphene oxide was functionalized with carboxylic acid groups via diazotization with 4-aminio benzoic acid and sub

Fluorescence properties and quantum-chemical modeling of tert-butyl-substituted porphyrazines: Structural and ionization effect
Synthesis and identification of tetrakis-[5,6-bis(4-tert-butylphenyl)pyrazino] porphyrazine, tetra-(4-tert-butyl)phthalocyanine and octakis-(4-tert-butylphenyl)porphyrazine were carried out. Spectrophotometric method was used to study the spectral, acidic

An easy route for the synthesis of pyrazine-2,3-dicarbonitrile 5,6-bis-substituted derivatives using a palladium catalyst
An easy synthetic method for the preparation of pyrazine-2,3-dicarbonitrile 5,6-bis-substituted derivatives using Pd-catalyzed cross coupling reaction (Sonogashira, Suzuki, Heck) is described. The reaction conditions allow preparing symmetrical and unsymmetrical bis-substituted products in moderate to high yields, as precursors for the preparation of highly substituted symmetrical and non-symmetrical aza-phthalocyanines with well-defined spectral properties.
