Highly efficient near-infrared emission from binuclear cyclo-metalated platinum complexes bridged with 5-(4-octyloxyphenyl)-1,3,4-oxadiazole-2-thiol in PLEDs

► A novel near-infrared-emitting binuclear platinum complex was prepared. ► We investigated the optophysical properties of the complex. ► The PLEDs presented a near-infrared emission with an external quantum efficiency of 6.3%. ► This work provides an efficient approach to realize near-infrared emission.
