Synthesis of Conjugated Polythiophenes with Azobenzene Substitutes in the Side Chains

Novel conjugated polythiophene derivatives with azobenzene moieties to attaching to the polymer backbone via a flexible alkyl spacer were synthesized by electrochemically direct anodic oxidation in boron trifluoride diethyletherate (BFEE). The physical, optical and fluorescent properties of the resulting polymers were characterized. As conducting and optical materials, the polymers can be promising in the field of photoelecrtonics area.
