AbstractA blended layer composed of a coil-rod-coil triblock oligomer and LiCF3SO3 was introduced into light-emitting electrochemical cells. The response rate and efficiency of the device were greatly improved, and a low operating voltage was maintained. The device, with a structure of indium tin oxide/PEO-PHP-PEO(LiCF3SO3)/[Ru(bpy)(3)](PF6)(2)/Au, showed a turn-on voltage as low as 2.85 V, while its luminance and efficiency were approximately twice those of a single-layer device. The power, luminance, and external quantum efficiency at 1000 cd/m(2) reach 2.1 cd/A, 1.5l m/W, and 2.6%, respectively. We attribute these improvements to the enhancement in the hole injection and electron blocking effect resulting from the blended layer. (C) 2008 American Institute of Physics.
