Oriented crystalline films of tris(8-hydroxyquinoline) aluminum(III): Growth of the alpha polymorph onto an ultra-oriented poly(tetrafluoroethylene) substrate
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 100degreesC. The scale bar corresponds to 1 mum.
