Little is known about the molecular pathway to monomers of semiconductor nanocrystals. Here, the authors report a general reaction pathway based on hydrogen-mediated ligand loss for the precursor conversion to ‘monomers’ at low temperature prior to nucleation, via 31P NMR spectroscopic measurements.
