有机发光二极管（OLED）中的蓝色电致磷光可以通过使用3，6-双（三苯基硅基）咔唑来增强（见图）。该咔唑衍生物具有大的空间体积和大的间隙三苯基硅烷基基团，是一种电化学和形态稳定的有效的蓝色电致磷光主体材料。当用于OLED中时，实现了高达16%、30.6 cd A（-1）和26.7 Im W-1的高效率。
Blue electrophosphorescence in organic light-emitting diodes (OLEDs) is enhanced by the use of 3,6-bis(triphenylsilyl)carbazole (see figure). This carbazole derivative with sterically bulky and large-gap triphenylsilyl groups is an electrochemically and morphologically stable efficient host material for blue electrophosphorescence. When utilized in OLEDs, high efficiencies of up to 16 %, 30.6 cd A(-1), and 26.7 Im W-1 are achieved.
