The structure-property relationships in mixed ligand d10 metals (i.e. zinc and cadmium) employing dithiol and N,N-heterocyclic ligands are continuing in my laboratories. Several unusual multinuclear compounds have recently been obtained and shown to be luminescent. Additionally, a novel luminescent trinuclear compound that exhibits multiple coordination geometries has been isolated and characterized. Further syntheses and studies of the factors that control five coordinate vs. four coordinate structures in these complexes are ongoing. Photophysical measurements have shown that in some cases multiple emissions are possible from a molecule and excited state studies of any luminescent species are always a primary goal of any aspect of this project.
Recently, my research group has started examining
luminescent trigold(I) complexes. Structural information shows
that luminescent properties of the pyrazolato, indazolato, and
pyridazinyl trigold(I) complexes are extremely sensitive to
electron-withdrawing factors (ligand basicity) as well as the degree of
supramolecular organization in the crystal.
An excitation-dependent emission has been observed in one unsymmetric
pyrazolato trigold(I) complex (See Figure).
