Abstract
Abstract Morphology and photophysical properties of DB‐PPV/PMMA blend luminescence ES fibers were tuned though various solvents and DB‐PPV content. The blend fiber prepared from solvents with different boiling points led to various aggregated morphology of DB‐PPV, such as core‐shell or wire‐like structures. The absorption and luminescence peak maxima were red‐shifted with the larger DB‐PPV aggregation size or increasing blend content, but the luminescence quantum efficiency showed a decreasing trend. Moreover, highly‐aligned DB‐PPV/PMMA blend ES fibers with polarized emission were successfully prepared using a modified collector design. The present study suggests that the morphology and photophysical properties could be efficiently tuned through solvent type and conjugated moiety content. magnified image
