Abstract:
Novel ligands for cyclometalated complexes that provide near-infrared emission are disclosed. The ligands contain strong electron-donating side chains such as alkoxy or alkylamine on a phenyl or naphthyl moiety which is linked by a covalent bond to the metal. This combination provides a significant red shift of the emission of the emitter.
