Light‐Emitting Diodes Article number 2200206 by Samuthira Nagarajan and co‐workers focuses on the design methodologies using triphenylethene‐ and tetraphenylethene‐based non‐donor–acceptor (non‐D‐A) and donor–acceptor (D‐A) structures for non‐doped blue organic light‐emitting diodes (OLEDs). In the non‐D‐A system, triphenylamine and carbazole‐based compounds demonstrate better performance, with the highest efficiency of 58300 and 5200 cd m –2 . In the D‐A system, imidazole‐based compounds display the highest efficiency of 65150 cd m –2 .
