Electron transporting layers comprised of organic free radicals are disclosed for use as the electron transporting layer in multi-layer structures that are useful for fabricating organic light emitting devices (OLEDs). For example, the multi-layer structure may include an electron transporting layer containing an organic free radical comprised of a multi-aryl-substituted cyclopentadienyl free radical of formula (I): ##STR1## wherein Ar.sub.1, Ar.sub.2, Ar.sub.3, Ar.sub.4 and Ar.sub.5 each are, independently of the other hydrogen, an alkyl group or an unsubstituted or substituted aromatic group. More specifically, included among these materials are those which are comprised of an electron transporting material based on, the pentaphenylcyclopentadienyl Cp.sup..phi.. free radical: ##STR2##
