^aMeasurements were performed with the solution isolated from FPLC (see Figure 2a).

^bHydrodynamic diameter determined by DLS.

^cLocal Pt(II) complex concentration calculated from ICP-MS (AES) data for Pt and S.

^dMaximum of emission determined by emission spectroscopy with excitation at 375 nm.

^eAmplitude weighted average lifetime determined by emission spectroscopy with excitation at 375 nm; τ error ∼1%.

^fEmission quantum yield determined with an integrating sphere; φ error ∼5%.

^gSize estimation by TEM was performed for nonspherical particles (see text) for the length and width (displayed in square brackets).
