Charge‐Transfer Complexes: Deep‐Red/Near‐Infrared Electroluminescence from Single‐Component Charge‐Transfer Complex via Thermally Activated Delayed Fluorescence Channel (Adv. Funct. Mater. 38/2019)

In article number 1903112, Liang-Sheng Liao, Chun-Sing Lee, and co-workers report the formation of dimeric single-component charge-transfer complexes (SCCTCs) by self-complexation of a donor-π-acceptor molecule (PIPAQ), wherein the strong intermolecular charge transfer leads to unusual deep-red/near-infrared thermally activated delayed fluorescence. Notably, PIPAQ can be applied in light-emitting devices as an emissive layer to realize unprecedented SCCTC-based electroluminescence.
