With the aid of in-situ absorption spectroscopy we performed a comparative study of the precursor route poly(pphenylene-vinylene) homopolymer and an acetoxy substituted copolymer derivative as a function of conversion temperature. It is shown that assuming a trans-cisoid conformation both polymers c

## Abstract Nโ€type doping of poly(2โ€methoxyโ€5โ€(2โ€ฒโ€ethylโ€hexyloxy)โ€pโ€phenylene vinylene) (MEHโ€PPV) with decamethylcobaltocene (DMC) strongly improves the electron transport due to filling of the electron traps. Unexpectedly, the nโ€type doping simultaneously suppresses the hole transport in MEHโ€PPV.
