Three blue materials based on diphenylamino dibenzo[g,p]chrysene were designed and synthesized via Buchwald-Hartwig amination. To characterize their electroluminescent properties, multilayered organic light emitting diodes (OLEDs) were fabricated with the following device structure: indium tin oxide (ITO) (180nm)/4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA) (40nm)/N,N′-diphenyl-N,N′-(1-napthyl)-(1,1′-phenyl)-4,4′-diamine...
Organic light-emitting diodes (OLEDs) typically have low out-coupling efficiency. In this paper, a solution-based nanoparticle layer is presented as a nanostructure to enhance the out-coupling efficiency of OLEDs. Silica nanoparticles (NPs) are randomly distributed on indium tin oxide by spin-coating a silica NP solution. By further spin-coating poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)...
