Crystalline films of tris(8‐hydroxyquinoline) aluminum( III ) (Alq) have been grown on poly(tetrafluoroethylene) (PTFE) substrates. The nucleating ability of the PTFE substrate, which relies on a specific molecular structure, is discussed. The Figure shows the film morphology of a 15 nm Alq film deposited onto an oriented PTFE substrate at 100 °C. The scale bar corresponds to 1 μm.
