ABSTRACT:
An org. light emitting device is described comprising (a) a substrate; (b) an anode and a cathode disposed over the substrate; (c) a luminescent layer disposed between the anode and the cathode wherein the luminescent layer includes a host and at least one dopant; (d) the host of the luminescent layer being selected to include a solid org. material comprising a mixt. of at least two components wherein (i) the first component of the mixt. is an org. compd. that is capable of transporting either electrons or holes or both and is capable of forming both monomer state and an aggregate state and further is capable of forming the aggregate state either in the ground electronic state or in the excited electronic state that results in a different absorption or emission spectrum or both relative to the absorption or emission spectrum or both of the monomer state, resp.; and (ii) the second component of the mixt. is an org. compd. that is capable of forming a continuous and substantially pin-hole-free layer; and (e) the dopant of the luminescent layer being selected to produce light from the light-emitting device.
