Extending El Sayed's Rule by 1 (n,π*)– 3 (n,π*) Rotation via Intramolecular Secondary Interaction Enables Room‐Temperature Circularly Polarized Phosphorescence in Solution

The development of purely organic chiral room temperature (RT) phosphorescent emitters is in the limelight. However, the key parameters governing the polarized luminescence are difficult to predict and rationalize since the phosphorescence emission is rarely obtained in solution, despite the
