EFFECT OF STRUCTURE ON THE PROPERTIES OF POLYCONJUGATED SYSTEMS

The modification of chemical structure may modulate the properties of polyconjugated system in order to optimize the applications in different fields. Many properties can be tuned ranging from the solubility to the band gap of the polymer. Moreover, the presence of a polar group in the side chain open new possibilities in the preparation of ordered molecular architecture such as Langmuir Blodgett films. We will discuss these parameters focusing our attention mainly on the preparation of Langmuir Blodgett films of poly(3-alkylthiophene) and of low band gap structure.
