Improved syntheses of some monochloro- and monobromo-8-quinolinols
摘要:
Procedures were developed for the preparation of the 2-, 3-, 4-, and 6-monosubstituted chloro and bromo 8-quinolinols which afforded greater yields and/or reduced the number of steps in the preparation. 100 MHz H-1-NMR spectra for the 12 possible monochloro and monobromo analogues are given.
The present invention relates to metal complexes and to electronic devices, in particular organic electroluminescent devices, containing these metal complexes.

The present invention relates to metal complexes and to electronic devices, especially organic electroluminescent devices, comprising these metal complexes, especially as emitters, and in particular monometallic metal complex containing a hexadentate tripodal ligand in which three bidentate sub-ligands coordinate to a metal and the three bidentate sub-ligands, which may be the same or different, are joined via a bridge.
