文摘

Voltammetric and spectroelectrochemical behavior of two newly synthesized conjugated polymers, which show the same chemical constitution but different type of regioregularity, is compared. These are poly(fluorenone-alt-dioctyl bithiophene)s in which the alkylthiophene rings are either head to head (HH) or tail to tail (TT) coupled, termed PFDOBT-HH and PFDOBT-TT, respectively. Both polymers can be electrochemically p- and n-doped and show the electrochemical energy gap ( Formula Not Shown ) of the order of 2eV. In the oxidation side of the voltammogram PFDOBT-HH gives a relatively narrow anodic peak with a maximum at E
