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-infrared electroluminescence.This work has been published online in the Nature Materials on July 22,2019.
