The successful fabrication of organic light emitting diodes (OLEDs) utilizing organic semiconducting polymer nanospheres was reported. The devices consist of a homogeneous single layer of nanosized semiconducting conjugated polymer nanospheres (SPNs) and reveal improved opto-electronic characteristics compared with "traditionally" fabricated OLEDs for which the active layer was cast from a solution of the conjugated polymer in an organic solvent. Optical spectroscopy have evidenced that conjugated polymers can be converted into aqueous SPN dispersions without generation of electronic defects; the SPNs display the photophysical properties of the bulk polymer.
