Abstract

Fabrication of discrete, structurally regular, highly ordered, nanoscale organic light-emitting diode (OLED) arrays using a variant of nanosphere lithography is communicated. We report patterning, imaging, and the device current-voltage-luminescence characteristics of arrays of OLED nanostructures (ITO/self-assembled N(p-C6H4CH2CH2CH 2SiCl3)3-derived injection layer/1,4-bis(1-naphthylphenylamino)biphenyl/aluminum tris-(8-hydroxyquinolate) (Alq): 1% N/N′-di-isoamyl quinacridone/Al) of a length scale previously unrealized (40-90 nm/side). Minimal alteration/ degradation of device response characteristics is demonstrated for OLED size compression to nanoscale, thereby offering new possibilities for nanoscale optoelectronic devices.
