Compounds of group 15 in the periodic table are useful ligands in inorganic and organometallic chemistry, especially tertiary phosphines and arsines. We have shown that the common ligating groups EPh3 (E = N, P, As) interact with the surface of CdSe in a manner consistent with adduct formation. Depletion width changes in the semiconductor reflect the relative basicities of these compounds, maximizing with PPh3. Adduct formation constants do not correlate with depletion width changes. The largest constant is found for AsPh3. The influence that these compounds have on the electronic structure of CdSe is discussed.
