✦ Synopsis

Poly(2-(2-ethylhexylthio)

-5-methoxy-1,4-phenylenevinylene) (PMEHTPV) was synthesized in thin films via a water-soluble precursor polymer and characterized with thermogravimetric analysis (TGA), FT-IR, and elemental analysis, etc. The PMEHTPV film could be stretched up to 10 times and showed conductivity of 0.13 Scm 01 when doped with FeCl 3 . The 2-ethylhexylthio group resulted in blue-shifted absorption and emission compared to those of poly (2-(2-ethylhexyloxy-5-methoxy-1,4phenylenevinylene) (MEH-PPV). The relative quantum efficiency of the device made by PMEHTPV was 20 times higher than that of MEH-PPV.
