摘要：

Two series of chiral cyclometalated iridium(III) complexes based on sulfur atom containing enantiopure BINOL derivatives were rapidly synthesized, which are endowed with varied chiroptical properties. Moreover, the circularly polarized OLEDs using enantiomers show a maximum luminance of above 40 000 cd m(-2) and an external quantum efficiency of 23.6% with low efficiency roll-off as well as obvious CPEL properties.
