Abstract	The dielectric nature of organic ligands capping semiconductor colloidal nanocrystals (NCs) makes them incompatible with optoelectronic applications. For this reason, these ligands are regularly substituted through ligand-exchange processes by shorter (even atomic), or inorganic ones. In this work, an alternative path is proposed to obtain inorganically coated NCs. Differently to a regular ligand exchange processes, the here reported method produces core-shell NCs simustaneouly to the removal of the original organic shell. This procedure leads to connected NCs resembling 1D worm-like networks with increased optical properties and polar solubility, in comparison with the initial CdSe NCs. The nature of the inorganic shell has been elucidated by X-ray Absorption Near Edge Structure (XANES), Extended X-ray Absorption Fine Structure (EXAFS) and X-ray Photoelectron Spectroscopy (XPS). The 1D morphology along with the lack of long insulating organic ligands and the higher solubility in polar media turns these structures very attractive for their further integration into optoelectronic devices.
