Trifunctional Light-Emitting Molecules Based on Rhenium and Ruthenium Bipyridine Complexes

Xiong Gong, The University of Akron


The synthesis and light-emitting properties of two novel, trifunctional, light-emitting molecules based on rhenium(I) and ruthenium(II) bipyridine complexes are described. The hole-transporting, electron-transporting, and light-emitting functional groups are incorporated into one molecule. The authors report that their approach provides flexibility since the optoelectronic properties can be modified by varying the ligand and/or the metal component. For example, a multicolor display is claimed to be possible by preparing mixed metal complexes.
