Highly efficient deep blue organic electroluminescent device based on 1-methyl-9,10-di(1-naphthyl)anthracene Available to Purchase

The author have developed 2-methyl-9,10-di(1-naphthyl)anthracene (⁠$α,α$-MADN) as an effective wide band gap host material for Förster energy transfer to the unsymmetrical mono(styryl)amine deep blue fluorescent dopant (BD-1). This guest/host emitting system, at the optimal doping concentration of 3%, can also increase the probability of carrier recombination near the hole-transport/emitting layer interface for the blue organic light emitting device which produces electroluminescence efficiencies of $3.3cd∕A$ and $1.3lm∕W$ and a deep blue $CIEx,y$ color coordinates of (0.15, 0.13) that are 50% better than those of the traditional $β,β$-isomeric host (MADN) with the same dopant.
