materials exhibit ambipolartransport characteristics in undoped OLED devices, and the charge conductivity of the devices was enhanced by increasing the fluorene ratios in the host molecules. Compared with phenylsilanes, the fluorenylsilanes show better hole injecting and charge transporting abilities. SiFl4 was investigated as a host material for red, green, and blue phosphorescent devices, giving peak
