When treating haloaromatic compounds with magnesium metal in the presence of transition metals as catalysts  the yellow PPP-material formed is superior to the black product obtained by oxidative coupling, but also possesses relatively low molecular weight (scheme 7 (3)). To achieve higher molecular weight it was unavoidable to improve the solubility by introducing functionalized starting compounds that carry additional solubilizing alkyl chains . Clearly, monoalkyl dihalobenzenes cause a regioselectivity problem, which can be avoided by using the corresponding 2,5-dialkyl compounds 6.
Regiochemical control to obtain the desired head-to-tail products is still missing for oligothiophenes exceeding three repeat units. This is due to the problems in obtaining isomer-free building blocks with a 2,4-substitution pattern. However, some differently functionalized, regioregular terthiophenes have been synthesized utilizing low-valent transition-metal catalysts . 6. Polypyrrole The main interest in polypyrrole (PPy) 21 stems from the excellent long-term stability of its conductive state as compared, for example, with that of polythiophene, and from the possibility of tailoring its properties by synthesis .
