Morphology-Dependent Ullmann C-O Arylation Using Cu₂O Nanocrystals

Figure 5

Relationship between the % conversion of the Ullmann coupling and (a) the binding energy of the Cu^I 2p_3/2 photoelectron line, (b) the apparent band gap energy of the different Cu-oxide nanocrystals, and (c) the correlation between the binding energy of the Cu^I 2p_3/2 photoelectron line and the apparent band gap energy of the different Cu-oxide nanocrystals.
