Novel light-emitting diodes using organic electroluminescent nanocapsules

Novel light-emitting diodes have been constructed using electroluminescent nanocapsules (ELCs) as the emitting layer (see Figure). The ELCs comprise electroluminescent perylene as a core with electron- and hole-transfer moieties in a polymeric shell, and were prepared by emulsion copolymerization, a technique that allows the properties of devices to be tuned via the appropriate selection of matrix polymer and other components.
