With a small molecule, however, it is challenging to realize two independent radiative pathways. We invented the first examples of dual\u2010emissive single\u2010benzene fluorophores (SBFs). Two emissive tautomers are generated by synthetic modulation of the hydrogen bond acidity, which opens up pathways for excited\u2010state proton transfer. White light is produced by a delicate balance between the energy and intensity of the emission from each tautomer. We show that the excited\u2010state antiaromaticity of the benzene core itself dictates the proton movements driving the tautomer equilibrium. Using this simple benzene platform, a fluorinated SBF was synthesized with a record high solubility in perfluorocarbon solvents. White light\u2010emitting devices and multicolor imaging of perfluorocarbon nanodroplets in live cells demonstrate the practical utility of these molecules.<\/jats:p>","DOI":"10.1002\/anie.202302107","type":"journal-article","created":{"date-parts":[[2023,3,14]],"date-time":"2023-03-14T15:59:55Z","timestamp":1678809595000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Single\u2010Benzene
