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 OLED with a FHWM of 35 nm and CIE coordinate of (0.161, 0.046) was obtained based on the fully twisting donor–acceptor molecule TPA–PIM.
