  Tiny flowers: A conceptually new method for fabricating polymer/Prussian blue (PB) hybrid flowers with ultrathin petals by using a CAICP technique has been developed. The PB hybrid flowers exhibit enhanced thermal stability, emit deep‐blue light, and are electrochemically active. Their intriguing microstructure and enhanced structure‐dependent properties make them potentially useful in nanodevices
