Abstract

In general terms, the present invention includes a light emitting polymeric material, the polymeric material comprising: (a) an electron transporting polymer; the electron transporting polymer in contact with (b) an electron blocking polymer, the electron blocking polymer incorporating a network electrode polymer. Such devices may be bilayer or multilayer devices, in accordance with arrangements known in the art. Likewise, the source of electrical current may be from any appropriate source having the electrical characteristics sufficient to and appropriate for the desired device make-up and application.
