The molecule under study Oligo Phenylene Vinylene (OPV) is composed of repeating unit phenylene (-[C.sub.6][H.sub.4]-, the benzene ring with two hydrogen atoms removed) linked by vinylene (-[C.sub.2][H.sub.2]-, ethene with two hydrogen atoms removed) (Figure 2).
In this study, we considered a model blend of poly(p-phenylene vinylene) (PPV) donor oligomers and phenylC61-butyric acid methyl ester (PCBM) and defined the "[pi]-active" region by selecting (by hand) a single PCBM and three nearby PPV chains to assess the penetration of a localized electronic state into the bulk region.

One approach for the preparation of optical polymeric materials has been to electrospin polymer blends [5], such as polyfluorene derivatives/poly(methyl) methacrylate (PMMA) and phenylene vinylene derivatives/PMMA, using a single solution spinneret for the purpose of reducing AIQ to enhance luminescence efficiency.
Among electrically conducting polymers, [pi]-conjugated linear polymers, such as polyacetylene, poly(p-phenylene), poly(p-phenylene vinylene), poly(phenylene sulfide), polypyrrole,, polyaniline and polythiophene, have attracted a great deal of attention because of their ability to achieve high electrical conductivity by doping[1-5].

found that a pi-conjugated polymer nanostructure can form stable bars of polythiophene, poly (p-phenylenevinylene), polythiophene vinylene, poly(p-phenylene), poly(p-phenylacetylene), and polypyrrole.

Polythienylene vinylene (PTVs) are one class of conjugated polymers that are very attractive for optoelectronic applications due to its relatively lower energy gaps compared to polyphenylenevinylenes (PPVs) and polythiophenes (PThs), and particularly its capability of forming regioregular polymers with high crystallinity in solid states [1].

Different types of polymers have been used in thermoelectric devices, such as polyaniline (PANI) [41, 42], poly(p-phenylene vinylene) (PPV) [43, 44], polyacetylene (PA) [33, 34], poly(2,7-carbazolenevinylene) [32, 45], and poly(2,5-dimethoxy phenylenevinylene) (PMeOPV) [40].
