✦ Synopsis
En route to real molecular electronics the “spectral hole burners” among physical chemists have come a long way. Two developments which foster these ambitions are discussed herein: 1. For the first time holes with sufficient thermal stability could be burned in experiments at room temperature by using the 4f electron transitions of Sm in substitutionally disordered microcrystals of SrFCl~0.5~Br~0.5~ or Mg~0.5~Sr~0.5~FCl~0.5~ doped with Sm^2+^. 2. The manipulation of single molecules necessary for real molecular electronics was possible on a perylene‐doped polyethylene film. At T = 1.5 K, spectral hole burning could be carried out selectively several times in succession with a single perylene molecule.
