Realizing Locally Excited Intermediate Triplets via Naphthyl Unit in Donor‐Acceptor Based Thermally Activated Delayed Fluorescence Emitters for Efficient OLEDs
An in‐depth understanding of locally excited (LE) intermediate states is crucial in regulating the reverse intersystem crossing (RISC) process and overall efficiency of thermally activated delayed fluorescence (TADF) emitters, directing rational material synthesis. Herein, we investigated the effect of incorporatin...
