标题:Metal 8-hydroxyquinoline-functionalized polymers and related materials and methods of making and using the same
发明人：WECK MARCUS; MEYERS AMY
权利人:GEORGIA TECH RES INST
摘要:This invention relates to the synthesis of Mq n -containing monomeric compounds, comprising a polymerizable moiety, an Mq n -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 Znq 2 - or Alq 3 -containing monomers, in the presence or absence of a co-monomer, provided a Znq 2 - or Alq 3 -containing polymer, which retained the optical properties of Znq 2 or Alq 3 in solution, respectively. The Mq n -containing polymers may be used in, among other things, the fabrication of light-emitting diodes (LEDs).
