Metal complex compounds are known, which form semiconducting discotic phases. The discoid molecules of these compounds form displaceable stacks in discotic, liquid crystal phases. An ultra-thin, higher-order film can be manufactured from these materials, however not the succession of two thin, differently doped layers because these would intermix at the temperature required for forming the columnar structure. The molecule disks are linked to form stack-shaped addition polymers by means of novel polyaddition components. On one layer made of p-conducting molecules, a second, n-conducting layer can now be applied without the risk of the layers intermixing, because the mobility of the large addition polymer molecules is much smaller than that of the individual disks in discotic phases. The polyaddition components are discoid molecules carrying a heteroatom on both flat sides, which is capable of forming a coordinative bond in the axial direction. These atoms form a bond with the central ion of the metal complex molecules such that a firmly interconnected stack is created. The novel addition polymers are semiconductor materials, and are particularly suited for the manufacture of photovoltaic cells and organic light-emitting diodes. |
