Notes:
The self-assembly of amorphous three-dimensional arrays of CdSe nanocrystals is probed in real time using multiple-reflection, infrared attenuated total reflection spectroscopy by following the solvent and the organic ligands that passivate the nanocrystal surface. During the self-assembly of a 250 ML array from pyridine-capped CdSe nanocrystals in pyridine solvent, the solvent molecules evaporate in ∼30–40 min and the pyridine-capping molecules leave the array very slowly, apparently limited by diffusion, with ∼30±8% remaining after three days. © 2000 American Institute of Physics.
