Useful:

• Description: 2CzPN is a highly efficient TADF sky blue emitter with two?electron-donating?carbazolyl moieties?attached to the?electron-withdrawing dicyanobenzene ring. The carbazolyl units are noticeably?distorted from the dicyanobenzene plane by steric hindrance,?leading to a small ΔEST?of 0.09 eV.
