With the parameters extracted from these solid samples, we were able to assess the selfassembly properties of the PNPls while in suspension in hydrocarbon solvents. Hexane is a commonly used solvent because it disperses well nanoparticles with large ligands such as oleylammonium or oleic acid. It is exactly this property that makes the self-assembly of PNPls into stacks difficult in this solvent. For this study, we chose samples Br-170 and I-110 due to their facility to assemble into a lamellar phase.
