摘要
We determined that the structure of the previously published highly efficient blue electroluminescent broate complex, lithium tetra (2-methyl-8-hydroxyquinolato) boron, does not contain boron. Rather, it is the lithium salt of 2-methyl-8-hydroxyquinoline. Copyright © 2003 American Chemical Society.
