FuD emission color tuning in luminogens constructed from tetraphenylethene,benzo-2,1,3-thiadiazole and thiophene building blocks

摘要

Full color luminogens are constructed from tetraphenylethene, benzo-2,l,3-thiadiazole and thiophene building blocks. OLED fabricated using one of the luminogens exhibits orange-red electroluminescence with high luminance and efficiencies of 8330 cd m~(-2), 6.1 cd A~(-1) and 3.1%, respectively. Synthesis of efficient blue, green and red organic materials has been the subject of intense academic research because of their potential applications in full color displays and white lightening devices. However, most dye molecules are highly emissive in the solutions but become weak emitters when fabricated as thin films, which has substantially hampered their practical applications.
