Near infrared-emitting tris-bidentate Os(<scp>ii</scp>) phosphors: control of excited state characteristics and fabrication of OLEDs

Abstract

Os(<sc>ii</sc>) complexes bearing chromophoric 1,10-phenanthroline, diphosphine and bipyrazolate ancillaries display efficient NIR emission ranging from 717 nm to 779 nm in the solid state at RT.
