Poly phenylene vinylene nanoparticles

The synthesis of poly(phenylene vinylene) (PPV) nanoparticles using ADMET has also been reported [47]. In this case, an aqueous emulsion polymerization was utilized, such that particle sizes ranging from 200 to 300 nm were observed. The molecular weights of the PPVs in this case were rather low (on the order of 1 kDa), but this was attributed to slow rates of reaction, rather than to the sensitivity of the catalyst species towards aqueous conditions. Despite having low molecular weights, these polymers demonstrated absorption and photoluminescence data that were consistent with those of previously reported PPVs. Some examples of conjugated polymers synthesized via ADMET are shown in Figure 20.3.

Hybrid films of ZnO nanoparticles and poly[2-methoxy - 5 - (3, 7 -dimethyloctyloxyl) -1,4-phenylene vinylene] (MDMO-PPV) have been characterized as a model hybrid bulk heterojunction photovoltaic cell [145].
