The syntheses and photophysical properties of PNP-based Au() complexes with strong intramolecular Au Au interactions
Herein we report the syntheses, X-ray structures and photophysical studies of the dinuclear dimeric gold( i ) complexes [ClAu(C 6 H 5 N)(PPh 2 ) 2 ] 2 ( 1 ), [Au(C 6 H 5 N)(PPh 2 ) 2 ] 2 [SbF 6 ] 2 ( 2 ) and [Au(2,6-Me 2 C 6 H 3 N)(PPh 2 ) 2 ] 2 [SbF 6 ] 2 ( 4 ). We have used ligands with different...

). We have used ligands with different substituents to see the effect of the substituents on the photophysical properties. All these complexes feature strong intramolecular Au Au interactions (2.7987-3.0056 Å) and were found to exhibit excellent luminescence properties with high quantum yields as well as different colors of emission.
We have prepared three fully supported PNP-based dimeric Au(
i
) complexes with intramolecular Au Au interactions and studied their photophysical properties. They exhibit various colors of emission with good quantum yields. |
