摘要：
Electroluminescent polymeric nanocomposite structures that are based on aromatic polyimides and cyanine dye nanosized crystals known as J aggregates and emit light in the IR region were prepared. For the first time, doped polymer systems were found to display IR luminescence whose spectrum had the form of a very narrow band that peaked at 1100 nm. Nanosized J-aggregate crystals in these new polymer materials act not only as effective acceptors of energy of excitonic states but also as active electron-hole transport sites.
