'-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
