Novel green light-emitting diode with high efficiency; Synthesis and electroluminescent property of poly(2-(2'-ethylhexylthio)-5-methoxy-1,4-phenylenevinylene) (PMEHTPV)
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(-1) when doped with FeCl3. The 2-ethylhexylthio group resulted in blue-shifted absorption and emission compared to those of poly( 2-(2'-ethylhexyloxy-5-methoxy-1,4-phenylenevinylene) (MEH-PPV). The relative quantum efficiency of the device made by PMEHTPV was 20 times higher than that of MEH-PPV. (C) 1997 John Wiley & Sons, Inc.
