Novel silane-based blue dopant for organic electroluminescent devices

Abstract

We have synthesized a new deep blue dopant (JTI) based on organic Silane fluorescent dye. Owing to the steric hindered characteristic of Silane moiety, the problem of dopant concentration quenching can be suppressed. When JTI was doped up to 15% in the stable blue host material 2-JTI JTI was doped up to 15% in the stable blue host material 2-methyl -9,10-di(2-naphthyl a luminance yield of 3.93 cd/A at 20 mA/cm(2) with a near saturated CIEx,y color coordinate of [0.15, 0.15].
