Highly efficient deep-blue OLED with an extraordinarily narrow FHWM of 35 nm and a y coordinate <0.05 based on a fully twisting donor–acceptor molecule†
Abstract
A highly efficient deep-blue organic light-emitting diode based on the fully twisting donor–acceptor molecule TPA–PIM exhibited a maximum quantum efficiency of 3% and a particularly narrow electroluminescence emission peaking at 420 nm with a full width at half maximum of only 35 nm and a CIE coordinate of (0.161, 0.046).
