Uniform nanofibers composed of poly[2‐methoxy‐5‐(2‐ethylhexyloxy)‐1,4‐phenylenevinylene] and its blends with poly(3‐hexylthiophene) are formed by co‐electrospinning their solutions with poly(vinyl pyrrolidone) (PVP) through a coaxial capillary system, followed by extraction of the PVP phase (see Figure). Compared with spin‐cast films, the fibers show reduced phase separation and improved energy‐transfer efficiency.
