An organic solution with a push–pull‐type fluorophore , which resembles the shape of a dragon in the cover image, exhibits aggregation‐induced emission enhancement upon water addition. The cover tells the story of one dragon who strayed into the mythical world. The dragon found water, which was poured by Ganymēdēs; he showered and drank the water. He then flew away swiftly, shining like the star sign Aquarius . Upon increasing the water content of the aqueous solutions, transformations from the monomer to the crystals and the crystals to the nanoparticles were observed, accompanied by emission enhancement.
