An improved multilayer light emitting device includes novel compounds for use as the electron transporting layer. In particular, the novel compounds are novel aluminum cheltates (e.g. tris(9-oxidophenalenone) aluminum [Al(9-opo).sub.3 ] and tris(6-oxidobenzanthrone) aluminum [Al(6-ob
Naked carbon nanotubes are dissolved in organic solutions by terminating the nanotubes with carboxylic acid groups and attaching an aliphatic carbon chain so as to render the carbon nanotubes soluble.
Naked single-walled nanotube carbon metals and semiconductors were dissolved in organic solutions by derivatization with SOCl.sub.2 and octadecylamine charge. Both ionic (charge transfer) and covalent solution phase chemistry with concomitant modulation of the single-walled carbon na
Naked single-walled nanotube carbon metals and semiconductors are dissolved in organic solutions by direct functionalization with amines or alkylaryl amines having an uninterrupted carbon chain of at least 5 and more preferably 9 carbon atoms in length.
