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.
When compared with 4CzIPN, 2CzPN has fewer carbazolyl groups which reduces its electron-donating ability and produces a shift of the emission maximum to shorter wavelength (473 nm).
