Polycyclic heteroaromatics with multi‐resonance (MR) characteristics are attractive materials for narrowband emitters in wide‐color‐gamut organic light‐emitting diodes. However, MR emitters with pure‐red colors are still rare and usually exhibit problematic spectral broadening when redshifting emiss...
