Abstract Single terrylene molecules doped into linear low‐density polyethylene can be oriented by tensile deformation of the matrix. In measurements on ensembles at ambient and on single terrylene molecules at cryogenic temperature, strong orientation along the stretching direction was observed by polarization‐resolved confocal microscopy. At cryogenic temperatures narrow and spectrally stable zero‐phonon lines were found. The low saturation intensity of 0.07 W cm −2 is consistent with an uniaxial orientation of terrylene in the sample plane.
