Short‐Wavelength Infrared Organic Light‐Emitting Diodes from A–D–A′–D–A Type Small Molecules with Emission beyond 1100 nm

. Furthermore, the NTQ-based OLEDs also possess sub-gap turn-on voltage of 0.85 V, which is close to the physical limits derived from the generalized Kirchhoff and Planck equation. This work demonstrates that A-D-A'-D-A type small molecules offer significant promise for NIR/SWIR emitting material innovations.
