Abstract

A new class of functional units for preparing charge transfer salts, based on π-stacks of a conducting oligomer in analogy to the well-known stacks of TTF units, is reported and provides a connection between CT salts and conducting polymers. The synthesis of the new water-soluble thiophene oligomer is presented and it is suggested that π-stacks may be present in some oxidized polythiophenes and similar polymers.
