RESUMEN

Blue light-emitting Au nanoclusters were synthesized in a simple one-pot process via reflux of Au ions with amino-terminated poly(1,2-butadiene) in toluene. DLS results and photoemission spectra showed that Au(8) nanoclusters were successfully formed. Moreover, photo-patterned films containing Au(8) clusters were prepared by photolithography.
