The impressive and unexpected long‐lived room‐temperature phosphorescence of boric acid (H3BO3) is unveiled by Peng Wu and co‐workers in their Research Article on page 9500. Unlike traditional metallic inorganic or aromatic organic phosphors, the phosphorescence originates from the weak conjugation of lone pair electrons from O atoms. The vacant pz orbital of B and the regular arrangement in the crystalline state with layer‐like packing through abundant hydrogen bonding are found to contribute to the long‐lived emission.
