Two luminescent platinum(II) complexes 1 and 2 containing extended π-conjugated cyclometalated ligands have been used as dopant materials for the construction of two high-efficiency organic light-emitting devices I and II. Device I (containing dopant 1) emits orange emission and exhibits a maximum external quantum efficiency of 12.4%, a maximum luminous efficiency of 32.3 cd/A, and a maximum power efficiency of 11.2 lm/W. Device II (containing dopant 2) emits yellow light and exhibits a maximum external quantum efficiency of 16.1%, a maximum luminous efficiency of 51.8 cd/A, and a maximum power efficiency of 23.2 lm/W.
