Blue-Gap Poly(p-phenylene vinylene)s with Fluorinated Double Bonds: Interplay Between Supramolecular Organization and Optical Properties in Thin Films

Blue-light-emitting poly(p-phenylene vinylene)s with fluorinated vinylene units are presented. It is demonstrated that self-aggregation governs the strength and polarization of the absorption spectra of thin films of these polymers. This indicates that self-assembly of the polymer chains in the films provides a means of tuning the electronic and optical properties of the pi-conjugated systems.
