Abstract

The invention relates to the technical field of phenoxazine derivatives, and particularly relates to 3,7-disubstituted phenoxazine derivatives and a preparation method thereof. Phenoxazine adopted asa raw material is subjected to a coupling reaction to synthesize N-(4-aminophenyl) phenoxazine; the N-(4-aminophenyl) phenoxazine is subjected to a nitration reaction to synthesize 3,7-dinitro-N-(4-nitrophenyl) phenoxazine; the 3,7-dinitro-N-(4-nitrophenyl) phenoxazine is subjected to reduction to synthesize 3,7-diamino-N-(4-aminophenyl) phenoxazine. The obtained 3,7-dinitro-N-(4-nitrophenyl) phenoxazine and the 3,7-diamino-N-(4-aminophenyl) phenoxazine can be structurally modified easily, and novel compounds having different functions can be easily synthesized from the same. The synthesized phenoxazine derivatives can be widely applied in materials, dye, photosensitized solar cells, and other fields.

Description

technical field

[0001] The invention relates to the technical field of phenoxazine derivatives, in particular to a class of 3,7-disubstituted phenoxazine derivatives and a preparation method thereof. Background technique

[0002] As early as more than 100 years ago, scientists began to study phenoxazine. Because phenoxazine molecules contain nitrogen atoms and oxygen atoms, both nitrogen atoms and oxygen atoms are electron-rich atoms, making phenoxazine a strong electron-donating unit. At the same time, the six-membered heterocyclic ring in the middle and the benzene rings on both sides form a special conjugated large Π bond system, which makes the molecule have high delocalization, rigidity, flexibility and stability. Based on the structural characteristics of phenoxazine, the molar extinction coefficient of phenoxazine is high, the absorption wavelength is in the near-infrared region, it has good water solubility and low biological toxicity, so it has been a hot spot in th...
