This invention discloses a phenylnaphthic acid derivative and its application in phosphorescent information encryption. The preparation method involves using 3,5-bis(ethoxycarbonyl)phenylboronic acid and methyl 6-bromo-2-naphthylcarboxylate as raw materials, and then performing a Suzuki coupling reaction under tetra(triphenylphosphine)palladium(O) catalysis to obtain the intermediate ethyl 2-(3,5-bis(ethoxycarbonyl)phenyl)-6-naphthylcarboxylate. This intermediate is then subjected to alkaline hydrolysis and acidification to obtain the target product, 2-(3,5-dicarboxyphenyl)-6-naphthylcarboxylic acid. This phosphorescent material has a simple preparation method, lower cost compared to noble metal phosphorescence systems, a simple guest synthesis method with high yield, and exhibits significant and stable phosphorescence effects. Furthermore, precise emission color control of high-performance doped thin films is achieved through the triplet-to-singlet Förster fluorescence resonance energy transfer (TS-FRET) mechanism, establishing a multicolor long-lifetime emission system. In addition, the material has multi-color adjustable properties and excellent long afterglow emission performance, showing great application potential in cutting-edge application fields such as multi-dimensional information encryption and high-end anti-counterfeiting.
