Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.

Exciton Splitting

ABSTRACTWe have determined the crystal structures of regioregular HH-TT oligomers with a variety of side chains, including hydroxy-bearing side chains capable of H-bonding. The H-bonding orders the molecular packing into infinite 2-D sheets of Φ-stacks. In these H-bonded sheets, the Φ-stacks are insulated from each other by the aliphatic side chains and form one-dimensional “wires”. In contrast, the structures of similar oligomers that do not have H-bonded side-chains feature a structure in which neighboring Φ-stacks in are in contact (“shorted wires”). The effects of these differing molecular arrangements on the spectral properties and exciton splitting are discussed.

Polaron Formation

The dynamics of injected holes in short transient times that precede polaron formation is numerically studied in the framework of a tight-binding electron–phonon interacting approach aimed at describing organic one-dimensional lattices.
