In the following, we will review some recent studies on highly oriented PPV films. PPV and its substituted soluble derivatives are among the most widely studied conjugated polymers as they show both good photoluminescence and charge transport properties. Moreover, the availability of high-quality, well-oriented PPV samples enabled to clarify some fundamental issues such as the assignment of the polarized optical transitions and the determination of the anisotropic dielectric functions . This knowledge is essential to eliminate spurious effects in spectra obtained with nonconventional polarized spectroscopies, which may directly probe intra- and intermolecular interactions.
