Structural and photophysical features of triphenylene–gold(I) phosphane complexes

Two series of mono- or dinuclear gold(I) complexes incorporating an ethynyltriphenylene chromophore and various mono- and diphosphanes have been synthesized and characterized to explore the interplay between the ligand structure, aurophilic interactions, and photophysical properties. The complexes d...
