  We electrochemically polymerized various achiral heteroaromatic monomers in left-handed helical cholesteric liquid crystal (CLC) media. Circular dichroism (CD) spectroscopy revealed that most of the resulting conjugated polymer films exhibited both the first negative and second positive Cotton effects near their absorption maxima. This indicates left-handed helical aggregation of the conjugated main

  我们在左旋螺旋胆甾型液晶（CLC）介质中电化学聚合了各种非手性杂芳族单体。圆二色性（CD）光谱显示，大多数所得共轭聚合物薄膜在其吸收最大值附近均表现出第一负棉花效应和第二正棉花效应。这表明共轭主链的左旋螺旋聚集，这与CLC的左旋螺旋顺序一致。该结果表明，在电沉积期间，左旋螺旋CLC环境引起聚合物的左旋螺旋聚集。然而，聚合物的CD强度取决于母体单体的结构。

  The invention relates to a method for the preparation of a polymeric shaped article containing an electrically conductive polymer, wherein a base shaped article containing a matrix polymer is contacted with an anode in the presence of an electrolyte-containing medium containing monomer units, which on polymerisation to form an electrically conductive polymer, and wherein a voltage is applied between the anode and a second electrode which is in contact with the electrolyte-containing medium. The method according to the invention is characterised in that the applied base shaped article possesses electrically conducting properties and that the contact between the shaped article and the anode is established by moving the article along the anode, at least part of the article being in contact with the anode. It has appeared that, in the method according to the invention, the shaped article does not adhere to the electrode so that the method may be practised continuously. A further advantage of the shaped article failing to adhere to the electrode is that the method according to the invention generates very little waste. Furthermore, it has appeared that the method according to the invention allows a shaped article to be produced with a very short polymerisation time, the electrically conductive polymer in which being homogeneously distributed. The applied base shaped article does not swell during wetting, so that the mechanical properties of the base shaped article do not deteriorate. As a result, if the method is applied, for instance, continuously, a higher rate of production can be applied.
