Abstract
'-ethylhexylthio)-5-methoxy-1,4-phenylenevinylene) (PMEHTPV) was synth esized in thin films via a water-soluble precursor polymer and charact erized with thermogravimetric analysis (TGA), FT-IR, and elemental ana lysis, etc. The PMEHTPV film could be stretched up to 10 times and sho wed conductivity of 0.13 Scm(-1) when doped with FeCl3. The 2-ethylhex ylthio group resulted in blue-shifted absorption and emission compared to those of poly( (2'-ethylhexyloxy-5-methoxy-1,4-phenylenevinylene) (MEH-PPV). The relative quantum efficiency of the device made by PMEHT PV was 20 times higher than that of MEH-PPV. (C) 1997 John Wiley & Son s, Inc.
