| Abstract | Reversible dimerisation reactions of electrochemically produced organic radical ions are used as a general model for the explanation of charge injection in conducting oligomers and polymers [1]-[4]. Our main interest in this field is to investigate the driving force of dimerisation in such structures. While detailed electrochemical studies of conjugated compounds have been presented by several groups [5]-[11], the number of spectroelectrochemical investigations resulting in more direct information on the structural situation during dimerisation is limited and the formation of s dimers has not been described by in situ techniques. Furthermore, a variety of structures is needed to understand the dimerisation as a general reaction of oligomeric systems. Thus monodisperse organic compounds with low molecular weight like naphthalene diimides [5], thianthrenes [6], bipyrrols [7], bithiophenes [8], and extended conjugated oligomers e.g., oligo(thiophenes) [9], oligo(phenylenes) [10], and oligo(pyrroles) [11] were used for such studies |
