Since ancient times, chemical knowledge has been used to produce and decrypt invisible books. In this article, through the experience of Agent Sun and his granddaughter, we not only propagate the chemical knowledge contained in invisible books to the public and describe how to make invisible books skillfully with common objects used in daily life, but also introduce organic fluorescent materials to popularize scientific achievements in new encryption, anti-counterfeiting, and decryption. Thus, this article communicates the importance of information security and scientific and technological progress, while cultivating an interest in chemistry.

Key words: Popularization of science, Invisible ink, Fluorescent materials
