Aligned photoluminescent fibers are formed by the self assembly of an oligo‐(p‐phenylenevinylene) derivative (OPV) in oriented liquid crystals (see figure). The aligned fibers of OPV show polarized yellow emission in the direction of the long axis of fibers. New types of electro‐optical and photonic systems can be visualized in the future as the polarized luminescence of these fibers is combined with the dynamic properties of the liquid crystals.
