Octa‐ and tetrafluorinated bisanthene derivatives were synthesized for investigating the effect of electronegative fluorine substitution on the structure and physical property of bisanthene. Notably, a triisopropylsilylethynyl‐substituted octafluorinated derivative exhibited strong fluorescence with high fluorescence quantum yield and excellent photostability. Moreover, the derivative self‐assembled to form bundles of long semicrystalline nanofibers exhibiting hole‐transporting properties, see the Full Paper by H. Yamada et al. on page 7000.
