Properly designed organic molecules where a π‐conjugated bridge is end‐capped by an electron‐donor and electron‐withdrawing group (push–pull chromophores) can show, under specific conditions, frequency‐upconverted lasing emission. Materials based on these dyes are therefore able to convert the emiss...
