Incorporating fluorenyl substituents into the 2,5-positions of silole rings generates efficient solid-state luminogenic materials. The electroluminescent devices made by using the substituted rings as host emitters show yellow light, with high luminance, current efficiency, power efficiency, and external quantum efficiency of up to 44 100 cd m−2, 18.3 cd A−1, 15.7 lm W−1, and 5.5 %, respectively (see figure).
