摘要：

Two pairs of CPL-active binaphthyl-pyrene emitters with good photophysical properties and excellent chiroptical performances can emit high brightness blue CP-EL. The theoretical calculation results show that R-/S-5 can form rigid helix pi-pi stacking in the aggregation state which may greatly contribute to g(EL) of CP-OLEDs.
