EXAMPLE - Iron(III) perchlorate hydrate (5.16 g) was dissolved in acetonitrile (140 ml) in Erlenmeyer flask (250 ml) to form an oxidant solution. ethylenedioxythiophene monomer (1 g) and hexa(dodecyl-polyethylene 870)-ethylenedioxythiophene of formula (II) (1 g) were mixed in a vial and diluted with acetonitrile (10 ml). This monomer mixture was then added to the stirring oxidant solution. The vial was rinsed with acetonitrile and the washings added to the reaction mixture. The color of this mixture changed immediately to dark blue and was accompanied by an increase in viscosity and volume of the mixture. The mixture was allowed to react under vigorous stirring for 48 hours at room temperature, to give the product. The product was isolated and purified to obtain hyperbranchedhexa(dodecyl-polyethylene glycol 870)-poly(block-poly(3,4-ethylenedioxythiophene))-hexa(dodecyl-polyethylene glycol 870) of formula (III) (41%).
