Spectral narrowing in amorphous molecular solid films of spiro‐type molecules such as spiro‐quarterphenyl (see Figure) is reported. It is demonstrated that introduction of the spiro linkage not only improves the processability and morphological properties but, for the molecules studied here, also suppresses concentration quenching, making these molecular solids attractive candidates for molecular solid‐state lasers.
