Their thermal, photophysical and electrochemical properties were fully investigated. The OLED devices with C1–C3 as host were fabricated to investigate their electroluminescent properties. Compound C3 obtained the best device performances with the maximum current efficiency of 45.2 cd A−1and the maximum power efficiency of 23.2 lm W−1for green phosphorescent organic light-emitting diodes.
