The formation of noncovalent interactions between d8 platinum centers is believed to play a key role in the unique photophysical properties observed for materials derived from platinum(II) complexes.  While these Pt-Pt interactions have been observed frequently in the solid-state, it remains an open question whether such interactions form in solution.  Using multiple spectroscopic and computational approaches we have uncovered direct evidence for solution aggregation, which we conjecture is mediated by Pt-Pt interactions. Moreover, crystallographic studies suggest that prior solution aggregation plays a significant role in determining the final solid-state structure and properties of these materials.
