All the attributes necessary for good OLED performance (see Figure), namely, high electroluminescence efficiency (5.4 cd A –1 ), long operational lifetime (10 000 h at an initial luminance of 100 cd m –2 ), and deep‐blue color (color saturation: (0.14, 0.13)) are demonstrated by an OLED incorporating a novel, composite hole‐transport layer and an emitter based on a new mono(styryl)amine dopant in the stable, anthracene‐based blue host material, 2‐methyl‐9,10‐di(2‐naphthyl)anthracene.
