Switching the heavy-atom effect in blue thermally activated delayed fluorescence emitters With the rise of all-organic light-emitting diode (OLED) technology, understanding the complex phenomenon known as the “heavy-atom effect” (HAE) is becoming increasingly important.

Twisted Acceptors in the Design of Deep-Blue TADF Emitters: Crucial Role of the Excited-State Relaxation on the Photophysics of Methyl Substituted s-Triphenyltriazine Derivatives Among the most popular approaches recently applied to design of blue thermally activated delayed fluorescence (TADF) emitters, the one utilizing alkyl substitution distorting acceptor or donor fragments seems to have very high potential and wide applicability to organic materials.
