Abstract

Abstract : Chiral NIR-light emitters [Pt(iqbt)( S -L n ) ] (1–4 ) were used as dopants to produce CP-NIR-PLEDs displaying λ em of 732 nm, η MaxEQE of 0.87–0.93%, and g EL of up to 10 −3 . Abstract : Based on the molecular design of the chiral NIR emitters [Pt(iqbt)( S -L n )] (1–4 ), the first examples of CP-NIR-PLEDs with both attractive NIR-emission properties ( λ em = 732 nm; η MaxEQE = 0.87–0.93%) and high dissymmetry g EL factors up to 10 −3 are reported.
