Arylamines with electron donating groups such as alkyl and alkoxy groups in the meta position on the aromatic ring change the polymerization temperature of the benzoxazine prepared therefrom and offer an opportunity for an additional crosslinking site (the para position on the aromatic amine can couple to a Mannich base generated by the opening of the oxazine ring of the benzoxazine or a methylene bridge generated by a degradation reaction). Naphthenic amines with an alkyl or alkoxy substituent on the 5th through the 8th carbon atom on the naphthalene ring can function similarly. The polymers for benzoxazines prepared from at least 10% substituted aromatic or naphthenic amines are useful due to low polymerization temperatures and higher Tg (glass transition temperature).

The invention relates to a phenoxazine dye and a photoelectric converter using the dye, and belongs to the technology field of phenoxazine dyes. The technical proposal is that: the chemical structure of the dye contains substituted phenoxazine and the derivative thereof as electron donors and different conjugated groups as bridging chains, wherein one end of the bridging chains are connected with different electron-withdrawing groups. An electron-donating group on a nitrogen atom and lone-pair electrons on an oxygen atom interact with a chromophoric conjugated system, thereby resulting in more easier charge transfer of the excited state of molecules and generating unique photoelectric property. The phenoxazine dye has good application performance in dye-sensitized solar cells, and can replace expensive noble metal photosensitive dye in dye-sensitized solar cells.
