摘要：
Two novel AIEgens decorated with fluorenyl and dimesitylboryl groups are prepared. They show high thermal stability and excellent solid-state photoluminescence efficiency. Sky-blue nondoped OLEDs are achieved based on them, affording remarkable electroluminescence efficiencies (12.2 cd A(-1) and 5.3%), ultrahigh brightness (92 810 cd m(-2)) and low efficiency roll-off (11.0 cd A(-1) at 1000 cd m(-2)).
