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 π ‐conjugated systems.
