-
Paragraph 0041-0045, (2017/08/02)
The invention relates to the technical field of compound preparation and particularly discloses a D-pi-A-type aminoazobenzene dye and a preparation method therefor. A chemical structural formula of the dye is defined in the specification, wherein R1 is hydrogen, methyl or methoxy; and R2 is hydrogen or bromine substituent. The dye has maximum absorption wavelength being about 405 nm, is remarkable in photochromic property, is matched with a 405-nm blue laser, and has high potential for use as a blue-ray disc storage medium.
