[2.2]paracyclophanes incorporated within poly(3-butylthiophene): synthesis and photoelectrical properties

The synthesis and photoelectrical properties of [2.2]paracyclophanes, containing conjugated acetylenic triple bonds in the linear side-chain, are described. These compounds were incorporated as an electroactive component within a conductive polymer, i.e. polv(3-butylthiophene). The blend showed a photoelectrical response higher than that of the neat polymer. Surprisingly, it was found that the application of an electric bias during the preparation of the blend led to an increase in the photocurrent.
