3,7-disubstituted phenoxazine derivatives and preparation method thereof
-
Paragraph 0048-0053, (2019/11/21)
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.

An efficient and versatile Pd-catalyzed tandem C-N bond formation between aryl halides and primary amines is developed. The transformation allows a one-pot synthesis of phenoxazine and phenothiazine derivatives with a broad range of substitution patterns from readily available precursors.

Paragraph 0041-0042, (2017/04/19)
The invention provides a diamine monomer containing a triphenylamine-phenoxazine structure, a preparation method and an application of the diamine monomer in preparation of polyamide, polyimide and polyamideimide which have electrochromic properties, and belongs to the technical field of organic chemistry. The preparation method comprises the following steps: firstly, carrying out nucleophilic substitution on phenoxazine with substituent and halogenated nitrobenzene in the presence of a catalyst to obtain a mono-nitrated compound which contains a phenoxazine structure; secondly, reducing the mono-nitrated compound which contains the phenoxazine structure by using hydrazine hydrate in the presence of Pd/C used as a catalyst to obtain a monoamino compound which contains the phenoxazine structure; thirdly, carrying out nucleophilic substitution on the monoamino compound and the halogenated nitrobenzene in the presence of the catalyst to obtain a binitro compound which contains the triphenylamine-phenoxazine structure; finally, reducing the binitro compound which contains the triphenylamine-phenoxazine structure by the hydrazine hydrate in the presence of the Pd/C which is used as the catalyst to obtain the diamine monomer containing the triphenylamine-phenoxazine structure.
