Alkynyl-Gold Carbazole Hybrids: Luminescence and Functionalization via iClick Reactions.

ABSTRACT: A series of structurally diverse gold(I) complexes bearing the 9-(4-ethynylphenyl)-9H-carbazole chromophore were synthesized, featuring mononuclear, dinuclear, tricoordinated, and supramolecular architectures. Their formation involved either alkynylation reactions or the reaction of polymeric alkynyl species [Au(C≡CR)]_n with auxiliary ligands. Notably, an equilibrium between bimetallic and tricoordinated species was observed when diphosphine ligands were employed, highlighting the dynamic nature of these systems. This equilibrium was found to be solvent-dependent, with the pure tricoordinated complex isolable in a nonpolar solvent. The triazole complexes were synthesized via iClick chemistry by reacting the carbazole-functionalized alkyne with azide-phosphine gold(
