4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Formula: C16H17Br

How to control the dipole orientation of organic emitters is a challenge in the field of organic light-emitting diodes (OLEDs). Herein, a linear thermally activated delayed fluorescence (TADF) mol., PhNAI-PMSBA, bearing a 1,8-naphthalimide-acridine framework was designed by a double-site long-axis extension strategy to actively control the dipole orientation. The horizontal ratio of emitting dipole orientation of PhNAI-PMSBA reaches 95%, substantially higher than that of isotropic emitters (67%). This unique feature is associated with the intrinsically horizontal mol. orientation of PhNAI-PMSBA and the good agreement between its transition dipole moment direction and mol. long axis. The PhNAI-PMSBA-based OLED achieves an ultrahigh optical outcoupling efficiency of 43.2% and thus affords one of the highest red electroluminescence with an external quantum efficiency of 22.3% and the Commission International de l′Eclairage 1931 coordinates at around (0.60, 0.40). In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Formula: C16H17Br).
