We report the dramatic effects of polymer chain isolation on the photonic properties of blue‐emitting poly(9,9′‐dioctylfluorene). The organic/inorganic nanocomposite materials with two‐ or three‐dimensional geometry and good barrier properties prevented photo‐oxidation by blocking the penetration of oxygen and moisture. The materials also reduced keto‐defects which generate non‐pure blue light, and greatly enhanced the EL output resulting from the hindered interchain interactions.
