4, 4 '-azodibenzoic acid phenanthroline dye eutectic and preparation method thereof

The invention discloses a 4, 4 '-azodibenzoic acid phenanthroline dye eutectic, the molecular formula is C38H24N6O4, the structural formula is a preparation method, and the preparation method specifically comprises the following steps: (1) putting 4, 4'-azodibenzoic acid, 1, 10-phenanthroline and a solvent into a reaction container together, putting the reaction container on a stirrer under a closed condition, and stirring for full reaction; and (2) sealing the opening of the reaction container by using tin foil paper, pricking a plurality of small holes in the tin foil paper by using a needle, standing and volatilizing until red transparent blocky crystals are separated out from the reaction container. The thermal stability of the dye eutectic is obviously improved compared with that of the dye, and due to the fact that the dye eutectic and 1, 10-phenanthroline molecules form the eutectic, the coplanarity of the crystal is enhanced, the fluorescence intensity of the eutectic is improved by nearly 6 times com
