INVESTIGATIONS OF THE ELECTRONIC TRANSPORT IN A NEW CONJUGATED POLYMER

We present studies on the DC-conductivity of a new, fully unsaturated carbon ladder-polymer, which we doped with AsF5, K and Rb. The structu re of the new polymer is based upon a collapsed fullerene, where every five-membered ring is bonded to three six-membered rings. This leads to a planarized, board-like structure for which we expect good transpo rt properties. We found a conductivity change over several orders of m agnitude after doping. Investigations of the temperature behavior of t he conductivity revealed, that currently used models insufficiently de scribe the transport properties. We applied more complex, heterogeneou s models, to describe the conductivity in the measured temperature ran ge.
