主　　题：Non-Aufbau Principle Organic Luminescence Radicals OLED 

摘      要：To solve the problem of stability of organic luminescence radicals, Li et al. proposed a new kind of organic luminescence radicals with non-Aufbau electronic structure by using donor-acceptor molecular structure. The stability of this kind of radicals was greatly improved and the high luminous efficiency was maintained. Using a non-Aufbau radical as the emission layer of an OLED, the maximum external efficiency of 5.3% has been achieved, which is among the highest efficiencies for pure organic near-intrared electroluminescence. This work has been published online in the Nature Materials on July 22,2019.
