Excimer laser ablation (ELA) of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), 3,4,9,10-perylenetetracarboxylic diimide (PTCDI), 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) and perylene with 193(ArF), 248(KrF) and 308nni(XeCI) beams results in formation of amorphous semiconducting polymer thin films consisting of fine particles on several temperature-controlled substrates. The structure and electric conductivity of each prepared film depend considerably on the target material, ablation wavelength and substrate temperature. The films prepared on substrates at 300°C by ELA at 308nm from PTCDA and PTCDI partially contain polyperinaphthalene(PPN) structure with conductivity ranging from 10-1 to 10-2 Scm-1.
