The discussion focuses on using voltammetry to determine energy levels in semiconductor nanoparticles suspended in a colloidal solution with an undecyl monolayer. A primary concern is whether the hydrophobic alkyl layer will hinder electron transfer at the electrodes. Suggestions include using phase transfer catalysts or micellar structures to mitigate potential issues caused by the hydrophobic envelope. The goal is to oxidize or reduce the nanoparticles in contact with the working electrode to identify the potentials for oxidation/reduction, thereby calculating the HOMO-LUMO energy gap. While the alkyl layer may slow down the process, it is suggested that it may not completely block electrical contact between the silicon core and the electrodes, especially if the alkyl layer consists of a normal alkane. The analysis will be conducted in an organic solvent, raising further questions about the solvation of the hydrophobic tails.
