Abstract
This invention relates to the synthesis of Mqn-containing monomeric compounds, comprising a polymerizable moiety, an Mqn-moiety, and an optional chemical spacer therebetween, wherein q, in each instance, comprises an 8-hydroxyquinoline residue, M is a metal such as Mg, Zn, Al, Ga, or In, and n is 2 or 3 as the valence of the metal requires. For example, the polymerization of Znq2- or Alq3-containing monomers, in the presence or absence of a co-monomer, provided a Znq2- or Alq3-containing polymer, which retained the optical properties of Znq2 or Alq3 in solution, respectively. The Mqn-containing polymers may be used in, among other things, the fabrication of light-emitting diodes (LEDs).
