TL;DR: The field of multinary metal chalcogenide nanocrystals has gained strongly increasing interest in the quest for novel narrow band gap semiconductors as discussed by the authors, which can be classified according to the obtained crystal structure.

TL;DR: Complementary measurements of the absorption properties, external quantum efficiency and charge carrier mobility indicate that enhanced charge separation in the ternary blend is at the origin of the observed behavior.

TL;DR: In situ X-ray diffraction using synchrotron radiation and combined 1D and 2D proton and carbon NMR analyses reveal that the generated dodecyl radicals lead to the formation of a new thioether species R-S-R, which is part of a ligand double layer, which consists of dynamically bound dodecanethiolate ligands as well as of head-to-tail bound R- S-R molecules.

TL;DR: In this article, the surface ligand exchange in the solid state of thin films of nanocrystals has been studied and it has been shown that a shift of several tens of meV of the NCs' HOMO and LUMO levels takes place upon surface ligands exchange, confirmed by FTIR spectroscopy.

TL;DR: The presented method gives direct access to short-ligand-capped NCs without post-synthetic ligand exchange and shows an increase by a factor of 400 compared to established dodecanethiol-capping CuInS2 NCs.
