    • The ratio of phosphorus containing products observed requires that 1 equiv of DDA, or other organic molecule, is oxidized to maintain the typical valences of the Cd and Se atoms within the cluster. The exact identity of the oxidation product is unknown (see Figure 4S in the Supporting Information).

    • Large errors are inherent to transmission electron microscope measurements of size at this length scale. The large degree of uncertainty reflects the challenge in measuring a sample that is both sensitive to air, as well as the electron beam and is not meant to imply a distribution in cluster diameters. This range is in good agreement with values previously reported for nanocrystals that absorb in this region of the visible spectrum.
