Preparation of low-dimensional conducting polymer films by UV light-induced deposition with excimer laser beams

Studies on preparation of low-dimensional conducting polymer films by two kinds of UV light-induceddeposition methods with excimer laser beams are presented. Polythiophene thin films are prepared from several thiophene derivatives by exoimer laser chemical vapor deposition (ELCVD) with 193nm (ArF), 248mn (KrF) and 308nm (XeCl) beams. A film with highly oriented fibrous structure is obtained from 2,5-dichlorothiophene (2,5-DCT) by ELCVD with a 193nm beam. Excimer laser ablation (ELA) of 3,4,9,10-perylenetetracarboxylicdianhydride(PTCDA) with a 308nm (XeCl) beam results in formation of semiconductive organic thin films consisting of polyperinaphthalene (PPN) structure on a substrate at 300 °C.
