Abstract:
A series of AIE active cyclic trinuclear complexes (Au3, Ag3, and Cu3) have been successfully prepared and elucidated by X-ray crystallography. These complexes showed excellent AIE properties and their quantum yields (QYs) were significantly increased compared to those of the free ligands. The remarkable solution induced AIE activity in atom-precise coinage metal complexes is still scarce, and this work opens a promising avenue for the development of easily prepared metal-based AIE luminogens with high emission efficiency.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
