Epitaxial growth of thiophene/phenylene co‐oligomers (e.g., see Figure) on uniaxially oriented poly( p ‐phenylene) (PPP) is reported. The emission properties of these co‐oligomer thin films are investigated and compared to those of films grown on quartz. Color‐tunable emission highly polarized along the direction of orientation of the PPP is observed in the former case, while isotropic emission occurs on the quartz substrate.
