Approaches for Fabricating Tri‐ and Tetraphenylethene‐Based Blue Organic Light‐Emitting Diodes Using Donor–Acceptor and Non‐Donor–Acceptor Molecular Architectures

Abstract

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.
