In the paper we present synthesis and characterization of new donor-acceptor thiophene derivatives (TDs) containing vinylbenzo[d]thiazole, vinylpyridine and 1H-imidazo[4,5-f][1,10]phenanthroline residues. Using CELIV method, electron and hole mobility have been studied in the polymer layers based on poly [9,9-bis(6diethoxyl-phosphorylhexyl)fluorine] (PF-EP) doped with the TDs. Polymer light-emitting diodes (PLEDs) containing newly synthesized polyfluorene (PF) as emitting layers and PF-EP/TD composites as electron transporting layers show higher brightness at 15V as compared with TD free PF-EP.
